The watch is certainly not bad for the price. But there are a few gotchas:
- The Android application for the watch cannot be force closed. It restarts itself.
- Using the QR code sends you to a website that Google Chrome says has malware.
- The screen flickers. I may have a defective unit, or it may be poor QC, or it may be cheap components (I mean come on, what do you expect for $17US?).
- It is not built around the Nordic nRF52832 like the P8. I know of no one (other than the manufacturer) who has software for it.
The speaker and microphone seemed okay. I was able to make a phone call and hold a conversation through the watch, with the phone in my pocket.
That was probably the coolest thing about it.
