Geiles Teil

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.

Anders Jonsson

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.
