I have been back and forth with customer support at xgear over issues of the dots and the proximity sensor, which is an issue at least on the old pebble blue model. It does work most of the time in visible light, but in a dark room it frequently fails. I have to say that customer support at xgear has been TERRIBLE and they have not said one way or another if they will replace it with the "improved" version. Their website was also claiming a new version without the dots and when I emailed them about it, they said oh that's only the white one, the blue one still has the dots. What a shady website! They didn't disclose anywhere on their site that it was only the white one that didn't have dots anymore. They claim they stand behind their product, but I have not seen it in action. Very disappointed with them
