I don't find it bright enough unless you're indoors. It still does show your workout when dimmed, which is good and works well when in the gym, but when using it outdoors the glare on the screen keeps me from seeing much of anything when looking at an angle. I wanted to use it for sports, biking, ect. but it's pretty useless for that purpose in many cases I've tried so far. This feature is a nice addition for people who are buying a new watch anyway, but I updated from 4 to 5 for this feature and for what I ended up spending I feel it was a waste of money. If it won't cost you too much to update, it's a nice feature to have, but if you have a SS model for instance and have to pay a difference of like $400 after selling your old one and getting a new one it's probably not worth it. Try one out and see for yourself.
