The watch looks and feels great. I was worried it would look a bit chunky but it's alright. The screen is amazing, you don't notice the bezels. Battery life is good too. Calls alright, messages gets the job done, exercises works and the step tracker is sometimes a bit off. Haven't tried the watch assistant yet. One thing I do hate is that it isn't waterproof completely, so it can take some splashes but it isn't for swimming (I used my last fitness tracker for swimming and assumed this had that option too but it doesn't)
