Ich finde das diese Uhr ein richtig tolles Spielzeug zum experimentieren und rumprobieren ist. Leider bekommt man keine Ersatzteile daher ist dies meine zweite Uhr. Bei meiner ersten ist der Akku aufgebläht und hat mir das Display aus der Uhr gedrückt. Dann ist mir das Display gebrochen. Noch habe ich keine Probleme und hoffe das es so bleibt. Der Akku lässt sich bei der jetzigen Version nicht einfach austauschen wie bei Version 1.0. Ich hoffe inständig das es bald Ersatzteile einzeln zu kaufen gibt.
It's a wonderful product.
Great product! Took a few days to get Micropython complile correctly for the extra storage and extra memory, but now it's already running a micropython version of "windows". It's a really great product for developers! (Delivery took a bit longer than I thought, but I also didn't pay any extras for faster delivery).
It is better than I assumed.
The T-Watch 2020 V3 is the best product that has ever changed my life. This watch has been helpful in improving my daily life. I was able to monitor all kinds of data using this watch. Additionally, I could receive notifications without having to look at the screen thanks to the vibration notification function. Finally, this watch is very stylish and can be customized to match my style, so I always wore it with confidence. Overall, the T-Watch 2020 V3 is a fantastic product, and I highly recommend it.
