There was a problem filtering reviews right now. Please try again later.
The only issue that I had was that the assembly instructions were sent to me via amazon support message stating that an error had occurred with my order. The link to the instructions pdf was a short hyperlink trail from that. Once found, however, the assembly instructions were easy to follow and very helpful. Again, though, it would have been easy to miss. They should at least include a QR code in the packaging that takes you to the pdf online. Now, while the assembly was fun and straightforward, the usability of the clock is not so great. The UI is composed of two buttons and a 4 digit lcd, and there are way too many features packed in. This makes for an unnecessarily complicated setup, and I was unable to figure out even how to set the time in the five or so minutes that I attempted to do so...
Granted, I was in a hurry, and when I get back to it, I don’t doubt that I will figure it out, but the confusing experience did leave me a bit annoyed.
On the plus side, there is a small battery onboard that keeps the time, so you don’t need to worry about keeping it connected to power.
Overall, as a useful clock, it does leave something to be desired, but I don’t think that that was ever the intention. As a soldering practice kit though, this is a great beginner project, and I would definitely recommend! The clear housing makes for a great display piece, and it’s fun to be able to say, ‘yeah, I made that!’

The kit was shipped to us in a padded envelope and arrived on-time in perfect shape. As shown in the photo, it came packed in a small cardboard box. The box is a great place to store the components as you put the clock together.
On the day the kit arrived, I was very impressed to receive an e-mail from the seller with a link to a PDF instruction manual. The manual contains assembly instructions, a parts list, operation instructions, and a schematic. The assembly instructions were clear with good photos, and because the schematic was included, I was able to trace thru how the clock works with my son.
The clock is well designed – it’s based around an STC11F02E microcontroller that is clocked by a 12 MHz crystal. The display is a 4-digit LED display and includes a proper voltage dropping resistor array to ensure that the LED display is run within its maximum ratings. The board runs off of a +5VDC supply and includes proper filtering and bypass capacitors.
The PCB and the parts in the kit are of good quality – all of the components went onto the PCB with no issues and the board was very easy to solder. My son did most of the soldering himself and he’s rather new to soldering. This board would be a very good kit to hone your soldering skills if you are a beginner at soldering.
The assembled clock powered up successfully the first time and is working great! We were able to set the time and turn the alarms on and off without any problem. So far, it is keeping good time, neither losing nor gaining any time in the three days it has been powered on. The alarm is quite loud, so if you wanted to, you could use this as your main alarm clock.
Bottom line, this is a well-designed, well-produced kit that is well suited for a beginner in assembling and soldering kits. We found it to be an excellent value. I highly recommend it.

The clock itself is odd. But it is good fun. Shows time, date, temp, and one more screen that I can't decipher for the life of me. Regardless, the shop needed a clock, now we have one there.
The clock is accurate, but two buttons to go through setting up perhaps a hundred options is a little daunting. The thermometer has a calibration feature, that seemed high end to me, but in the end it didn't do what I expected. I would set it, but in a few minutes it would be off by ten degrees (F) or more. The hardest part of this kit is not building it, LOL.
Please remember to get the PDF here, don't use the QR code at on the instructions sent with the kit. Before I saw the link here at Amazon I had written the address on the instructions I did get. Pirates wrote back, don't bother writing them. The QR code leads to a site that is flagged by Virus Total.

The document available by request from the supplier is very well laid out and clear to follow for the building of the device. The instructions in the same document to actually use the finished product are difficult to understand due to the poor explanation.
