I had gotten myself a hybrid and was disappointed by it pretty quickly. So it doesn't surprise me that they didn't sell well.
IMO it didn't do good in both categories, smart features were lackluster and not well implemented. And the watch part was kinda OK but not good enough. I couldn't tell the time exactly and the hands had to calibrated often.
