calling via phone seems to really work
the watch shows the correct time
The sauce button works too
The system in the watch runs smoothly
it's nice that whatsapp works, but only if it's open 😂 it's a joke that even a video call won't wake up the watch.
video call via app? you can dial your phone with your watch, but do you think the app will ring? not a fart.
notifications of new messages, calls? Why isn't it on the main page? it's definitely every kid goes straight to the alert section.
a terrible little kid. this is not really how I imagine a 3k product, hopefully

Hello, thank you for your suggestion, on the basis of which the supplier contacted us and would like to respond below.
"If WhatsApp doesn't alert you to messages, the watch probably doesn't have stable data. We recommend using mobile data from a SIM that is still active. If the app does not display the video call, it is caused by one of the following factors. 1. You have installed an antivirus program 2. You have removed the background application 3. You have activated battery saving on the CARNEO GUARD application. Make sure your app is running in the background-activate it by pressing the bottom left "three commas" button, tapping the app icon and selecting lock app. Also enable application autostart: application settings - CARNEO GUARD - permissions - autostart. Also, please adjust the settings-applications-power-mode unlimited. For communication, we recommend the "Chat" function, where messages are displayed directly on the screen and remain there until the child reads them. SMS

Overall, I really like the idea. All the more so because it was apparently created by brothers in Slovakia - which pleasantly surprised and delighted me. Unfortunately, the HW is probably not of good quality. I believe that if they work on it, it could be a really great watch. The watch would deserve a 1* due to the non-functionality, but I'm rooting for the brand to improve.
Great idea and functionality, if it worked (see below).
Possibility to set up virtually all options for setting the watch remotely via phone, including e.g. time schedule for each application.
Wide functionality.
HW quality
I bought one watch that stopped charging after a few days of use. After a warranty claim, I got a new watch, which stopped working completely after a couple of hours of use (couldn't turn it on).
They are really huge - bigger than my not-so-small (men's) adult watch. I wanted to return them for that reason, but I found that there aren't many better alternatives on the market.

Ideal for a child if you do not want to rush the mobile. camera weaker, otherwise all fine.
ideal for teenagers if you don't want to rush your mobile
everything described works as expected
price corresponds to quality
the offered 20mm straps do not fit, the fit is 4mm wider

I wouldn't buy next time
Lots of features
Unnecessarily large for a child's hand. Watch app a big disappointment. We especially needed the health part and it is not working as presented.

It's the best watch we've tried so far, but even so it doesn't meet my expectations. But I haven't found anything better yet that isn't a phone. Most of the things really work and the child can call, text or, more often, record an audio message from them. It's all on data and there's not that much limitation in the number and it doesn't waste credit.
It is definitely the best baby control product yet
Leaving the zone really works and the messages come through well.
The first GPS that works even a little bit
Lots of advanced features
Easy to use
Multiple graphical menu and display layouts
No downright playful things to distract the kids
Solid battery life
Really huge watch - bigger than my AW ultra (it looks even bigger on a child's hands)
GPS is not 100% here either - but much better than other models
A bit annoying app - I have to log in every time I open it (data is pre-populated, notifications come without problems)

Don't buy it. The battery drops from 100 percent from evening to morning by 25 percent. During the day, you make a few calls 3 times and the battery is dead. Poor quality production
only negatives
weak battery
a hacked system.

I can't say that I'm unhappy with the watch. The GPS works well, the location is accurate and the localization can be relied on. The advantage is also SOS button, zone setting, alarm, English, math, schedule... just that the watch has a lot in it. For example, the system of rewarding with hearts has been successful in our country. I thought it was stupid, but my daughter likes it.
Watch
Probably nothing.
