    Good Looking, Capable Watch, Built to Last
    First, why I purchased the T-Rex Pro has everything to do with the two digital watches I had before I purchased the T-Rex Pro. Bear with me. More details about the watch itself below that.HUAWEI GT 2EMy 1-year old HUAWEI GT 2E watch strap broke and fell into a trash dumpster, which I didn't notice until it was too late. The $130 Huawei digital watch needed $4 screen protectors which broke almost bi-week, and the watch face eventually scratched up once I stopped replacing the protectors. The lesson here for me was that I wanted something more durable, similar to the Garmin Fenix 3 I had for 5 years prior to this watch.GARMIN FENIX 3My $650 Garmin Fenix 3 had come with a Saphire un-scratchable watch face. I loved this watch, treated it like a beast until the battery died (which is un-replacable). The memory for my love of the Fenix 3, with the bulky feel, and durable, sporty look, brought me to the T-Rex Pro, which is far less expensive. I was able to purchase the T-Rex Pro with a discount on amazon for $154.T-REX PROI've had the T-Rex Pro for several weeks, notably while moving locally and put it through an initiation where I accidentally clanked it against several doorways while walking with jumbo boxes in hands and it came through without a mark, even in one case having white paint stuck to the bezel from a wall where I had to peel off the paint with a utensil from the watch bezel. But no scratches through the 5 day ordeal despite the bezel hitting various doors, etc. The raised bezel no doubt has protected this watch face where the Huwei had failed time and again. As far as I can tell the watch face should hold up well without screen protectors.In terms of features, I've seen several reviews incorrectly state that you can only run one app on the watch at a time. They say, for example, if you've started the timer then you can't use the stopwatch, etc. Not true. When you have an app working on the watch just LONG-PRESS the "BACK" button and it will bring you out of the current app and back to the watch face where you can go back into your app list to select another app to use and run while the other one is working. It is possible to use multiple apps at the same time.I mostly use the watch for notification for calls, emails, and texts. It does an adequate job for this. I don't need to respond to them but just see what I need to get to while I'm out and about. The pop up notifications to alert you to a new text/email are a little too quick before disappearing for my tastes. When using the Notifications app to read an individual text/email, the messages are again on screen for only a few seconds before automatically kicking back out to the list of texts, so I need to go back and select/open the text again to get whatever part I missed. Also, a word in a text message will sometimes be broken up over two lines. It's not a huge deal in terms of functionality for but I also think it's something that should be fixed as it isn't professional look IMO. I can get past these small issues personally but you should know about them before purchasing this watch all the same.I love the look of the watch: the blue color suits me well and I like how the band feels more integrated with the overall look of the watch with the raised texture on the side of the band. In some online video reviews the blue watch color sometimes seemed a little greenish depending on the lighting but in personal it’s more of a matt blue grey which I do like and am pleased with. Please note, I've seen some people say there aren't replacement bands for this watch because they don't use the quick release mechanism on the band. You CAN purchase aftermarket bands for this watch but those bands require two small screw drivers (usually they come with the replacement band) and this was the very same process I used with my Fenix 3. The feel of the watch is good on the wrist and it's not too heavy. My fenix 3 had real heft to it which I kind of liked and wouldn't mind if the T-Rex Pro was even heavier. I imagine though most people would prefer the lighter feel of this watch.I downloaded a watch face that reminded me of one I had on the Fenix 3. I used the "AmazFaces" app from the iPhone store for a much wider selection of faces to download. Make sure in the T-Rex Pro "Zepp" watch app to toggle the watch setting for "Discoverable" to "ON" to be able pair and download watch faces from the AmazFaces app.The battery is very good. I still won't use an Apple watch because I don't like taking off my watch at night to charge and I like the option of not charging the battery for more than a few days. For instance, I misplaced my charger while moving, so I simply turned off all of the notifications, monitoring and special features, etc and I went 8 days using only 25% of the battery. But, should I turn all monitoring/features on such as heart rate, notifications, watch face always on, etc, I can use well more than 10% in a day. I like being able to adjust and balance what I want to use on the watch and keep a happy medium to battery length.All in all, I feel I have everything I wanted with my Fenix 3 at a big discount (sacrificing a little bit of the glitz of having a silver bezel, and the sports app, etc) but still have the pleasant feeling of a rugged watch that will give me a long battery life, take a beating, and provide the features I want.

      I've had the T-Rex Pro for several weeks, notably while moving locally and put it through an initiation where I accidentally clanked it against several doorways while walking with jumbo boxes in hands and it came through without a mark, even in one case having white paint stuck to the bezel from a wall where I had to peel off the paint with a utensil from the watch bezel. But no scratches through the 5 day ordeal despite the bezel hitting various doors, etc. The raised bezel no doubt has protected this watch face where the Huwei had failed time and again. As far as I can tell the watch face should hold up well without screen protectors.

      In terms of features, I've seen several reviews incorrectly state that you can only run one app on the watch at a time. They say, for example, if you've started the timer then you can't use the stopwatch, etc. Not true. When you have an app working on the watch just LONG-PRESS the "BACK" button and it will bring you out of the current app and back to the watch face where you can go back into your app list to select another app to use and run while the other one is working. It is possible to use multiple apps at the same time.

      I mostly use the watch for notification for calls, emails, and texts. It does an adequate job for this. I don't need to respond to them but just see what I need to get to while I'm out and about. The pop up notifications to alert you to a new text/email are a little too quick before disappearing for my tastes. When using the Notifications app to read an individual text/email, the messages are again on screen for only a few seconds before automatically kicking back out to the list of texts, so I need to go back and select/open the text again to get whatever part I missed. Also, a word in a text message will sometimes be broken up over two lines. It's not a huge deal in terms of functionality for but I also think it's something that should be fixed as it isn't professional look IMO. I can get past these small issues personally but you should know about them before purchasing this watch all the same.

      I love the look of the watch: the blue color suits me well and I like how the band feels more integrated with the overall look of the watch with the raised texture on the side of the band. In some online video reviews the blue watch color sometimes seemed a little greenish depending on the lighting but in personal it’s more of a matt blue grey which I do like and am pleased with. Please note, I've seen some people say there aren't replacement bands for this watch because they don't use the quick release mechanism on the band. You CAN purchase aftermarket bands for this watch but those bands require two small screw drivers (usually they come with the replacement band) and this was the very same process I used with my Fenix 3. The feel of the watch is good on the wrist and it's not too heavy. My fenix 3 had real heft to it which I kind of liked and wouldn't mind if the T-Rex Pro was even heavier. I imagine though most people would prefer the lighter feel of this watch.

      I downloaded a watch face that reminded me of one I had on the Fenix 3. I used the "AmazFaces" app from the iPhone store for a much wider selection of faces to download. Make sure in the T-Rex Pro "Zepp" watch app to toggle the watch setting for "Discoverable" to "ON" to be able pair and download watch faces from the AmazFaces app.

      The battery is very good. I still won't use an Apple watch because I don't like taking off my watch at night to charge and I like the option of not charging the battery for more than a few days. For instance, I misplaced my charger while moving, so I simply turned off all of the notifications, monitoring and special features, etc and I went 8 days using only 25% of the battery. But, should I turn all monitoring/features on such as heart rate, notifications, watch face always on, etc, I can use well more than 10% in a day. I like being able to adjust and balance what I want to use on the watch and keep a happy medium to battery length.

      All in all, I feel I have everything I wanted with my Fenix 3 at a big discount (sacrificing a little bit of the glitz of having a silver bezel, and the sports app, etc) but still have the pleasant feeling of a rugged watch that will give me a long battery life, take a beating, and provide the features I want.

      I've had this T-rex long enough now to write a brief review . Several months .
      There are videos showing the features so I'll stick to basic concerns prospective buyers may have .
      I was considering purchasing a Garmin smart watch but figured I should buy a less expensive offering in the case I ended up not wearing the thing very often .

      This watch is very light weight and I forget it is even on my wrist . It is large but very comfortable and I have a small wrist ; about 6 1/3 inches diameter .
      The keeper on the band that secures the excess portion of the band beyond the buckle incorporates a small protrusion that interlocks with the holes in the band and prevents it from sliding around and allowing the band to flop free like every other watch band I've owned . I wish this was a feature on all polymer bands !

      I charge the battery to 90 % and recharge it when it gives me a warning @ 10% charge .
      It requires one hour to charge from 10 to 90% .
      I use the GPS function twice a day for cycling for a total of maybe 1 hour to 1.5 hours total / day and operate the watch with the screen normally off and the battery lasts about 15 days , although sometimes it will go 23 days if I'm only wearing it 5 days a week .
      I'm guessing it will last you at least 5 days if you are using the heck out of it each day , but it charges so quickly battery life should not be a concern .
      I do not sleep with it so I cannot comment on those features .

      The GPS is accurate as far as tracking your movements on the map but don't buy this watch if accurate elevation data is important to you .
      I assume the internal clock is not accurate enough , it will give you very wrong elevation numbers each time you ask for it .
      The only thing I would like to be improved is that when using the countdown timer or stopwatch the watch does not display the time ( or anything else ) . You must cancel the function completely to view any other data .
      Overall this is a very capable device for such a low price . Very easy to operate .

      Watch works great and holds a very long charge.
      Only complaint is the part shown on the band. Everything else is very sturdy. Broke after only 4 months in my sleep.
      A discounted replacement (stronger replacement that is) would be greatly appreciated.
      I see I’m not the only one to experience this problem either.

      Llegó muy bien embalado, me gustó el reloj, no es muy robusto lo cual lo hace perfecto, bastante práctico, es fácil emparejar con mi Xiaomi, lo único es que hay que actualizar algunas veces porque como que se desconecta, pero no es un gran problema!

      I've had this watch for almost a week and, surprisingly, I have only charged it once even though I use it every day, and the battery is still at 64%. Additionally, the features that come with this smartwatch are good enough. Honestly, I don't miss anything from my Apple watch. It may be a bit basic on the notifications, but that's good for keeping me more focused and avoiding distractions.
