You guys kidding? There's a whole subculture of Casio's users, don't think any of those Casio's geekies will prefer a Garmin rather than an Android Wear powered rough G-shock from the heart. So far so good. Way to go Casio.
Casio sucks. It does not worth $500. Perhaps $100-150 sounds more reasonable.
A low spec, black plastic watch is at best worth $99. Trying to sell it for anything more is just cheeky! There will be few (none) buyers for this product.
