The accuracy of locating the child wearing the watch is disappointing. It shows at least 3 squares away. The quality of the material is satisfactory. You can of course talk to the child and vice versa, either through voice call, voice message, or even text message through the mobile application. In general, the child can communicate with you in case of danger without needing to have a mobile phone. It operates with a SIM card (preferably with a connection). If it had a better signal, it would be ideal considering the relatively small purchase cost.

The connectivity is terrible...

It only makes calls if you have talk time, unlike others that only need data.

And the main thing, I repeat, the connectivity is 0/10. It's purely a matter of luck when it will work to get the settings you will make in the application.

Relatively good watch, but a SIM card is necessary in case of time change (manually since it cannot be done automatically). The screen resolution is relatively low.

Medium difficulty in setting up and communicating with the mobile application. The rubber that protects the charging port broke quite quickly. No accuracy in finding locations on the map. After 2 months of use, the lens got stuck in the on position and does not close even with a restart.

Personally, I did not know that the use of a sim card is necessary for certain important applications to function. Without a sim card, even the time and date cannot be set. So I had to return it. Overall, though, and except for the above, it is a very good watch in relation to its price.

The GPS may only work in China. It shows me whatever it wants. Messages and shutdowns, nothing more. I was not satisfied. After two weeks, it started not to hold the battery, from 100% to 0 in 3 hours. Ridiculous
