    5.0 out of 5 stars Great smartphone detox
    Reviewed in the United Kingdom on July 8, 2021
    I looked around at various phones that would enable me to detox from the ridiculous amount of screen time I was racking up on my smartphone (Google Pixel 3aXL). I considered options from Nokia and others, and reviews seemed to be a mixed bag (as they do for this to be fair).

    I thought I'd give the B35 a go. I didn't want to spend more than £100 and at £85 this seemed pretty good value. Ordered on a Monday for free delivery by Thursday, and it arrived early on the Wednesday which was an exciting surprise.

    Out of the box the phone seems pretty well made. The outer shell is a sort of rubberised plastic (which I've since noticed does seem to attract smudges but most phones do) and a nice overall design to my eye. A case of form follows function methinks, which is quite appropriate given the CAT branding. Size wise it seems small, but a phone of this type would do coming from a large smartphone like the 3aXL. I've added a photo of it next to a tin of Pepsi for reference. I'd be happy to chuck this in the bottom of a rucksack / go camping with the kids etc - it just seems more rugged than my smartphone.

    On start up the phone displays the CAT logo and you hear the sound of a CAT engine starting up. My 3 boys think this is amazing and that I'm really cool, but it's grating on me already and I can't see a way to disable it in the menu. It's not a big problem - I just usually use the light of my phone screen to make my way to bed without putting the light on to wake my wife, and then turn it off - and I don't think she wants to hear the sound of a CAT C-11 engine at 1am.

    I wasn't sure from the advert and ordered a nano-sim adapter but this was a horrible waste of £2.49 - the phone had one already in the slot. It connected to WIFI easily, and recognised the EE network with no issues.

    The OS is pretty intuitive, and once muscle memory has kicked in for thumb texting with predictive text, it's a pretty smooth process to operate.

    WhatsApp works with no issues - although no video calling which I was aware of. For me, WhatsApp was a must have and the fact that is works so well on this is great.

    I tried to get my Apple @me.com email added to the native email app on the phone, but no luck. I'm not certain this is the phones fault, as I've struggled to get it working on other non-Apple devices too. I set up another free email address and it worked fine.

    I transferred my contacts seamlessly in 2 minutes via bluetooth which never happens to me - it always takes 4 hours.

    From the home screen you hit the left arrow to see 4 'quick access' apps. These are the KaiOS store, google assistant, google maps and Youtube. I can't see an option to change these which is slightly frustrating. I'd prefer WhatsApp & messages to live there (I've no interest in using youtube on the phone - which was a good part of my motivation to ditch the smartphone). That being said, there is a dedicated 'notices' shortcut from the home screen which shows any WhatsApp notifications / emails etc and this seems to work very well.

    What else can I say? There's really not a lot to it. It is what it is. Here's a summary of my Pros and Cons

    PROS

    1) It works
    2) It's not a smartphone
    3) It's not a "dumbphone" either (eg Youtube, Google Asst etc)
    4) Decent battery life (also because you have less reason to use it. I'm 2 full days from a 100% battery and now on 73% so seems like it could last a week no problem)
    5) Good option for a smartphone detox
    6) Not that expensive
    7) Intuitive OS
    8) You will feel very nostalgic depending on your age
    9) You will not be harangued by notifications every 14 seconds
    10) Seems rugged
    11) If a survival situation necessitated you sending a WhatApp message while underwater, you could do it

    CONS

    1) Older style screen means you need to be looking straight on to get the best viewing angle. No big deal really
    2) It makes excavator noises on start up and shut down
    3) Not able to select your apps for the home screen 'dock'
    4) If you are a chatty Cathy on the keyboard, you might find this frustrating even with predictive text. However if you're not, you now have an excuse for your one word answers

    Can't think of anything else.

    Don't buy it if you are intending to sit and watch YT etc
    Do buy it if you want a basic feature phone, that's still 4G and has WhatApp - as well as Google Maps etc to get you out of a pickle.

    I'm keeping my smartphone just in case but looking good so far.
