I got this watch and it seemed good, until I plugged it into my computer (macbook pro). My computer shut off, then I turned it on and plugged it in again. I got a warning that said it was drawing too much power and it disabled the usb. so i plugged it into my other mac (desktop). I got the same warning. Then I plugged it into my brother's pc. Then it worked. It is hd, the camera seems to record at a little funny angle. the bad thing about it is it's so gigantic. I have a small wrist, and this thing is huge. It causes questions like: "Wow your watch is big, wait a minute what is that blinking light?" Other then that it works pretty well and I like it
