I guess I am in the relative minority here since I didn't get the green version gd350-8 or the negative one, as I always prefer the clear lcd interface without color. So far this watch is fantastic and I particular like the one-touch timer function. Some users reported the "touchy" start button issue but luckily I haven't noticed it yet. The LED backlight is very good and not too bright at least for my eyes.
Another thing I want to report, besides those good things which have been reported by many usesrs here, is the remarkable viewing angle. I posted a comparison pic with my beloved gwm5610 and you can clearly see compared to 350 my puny 5610 runs away crying in shame...
Also, if you turn on the backlight, you can see the upper part in the display is actually in red color, which is pretty nice.
So far so good, like it very much and will very likely be my daily wear in future:)
