I gave them three stars but will keep buying them. In fact, they are very good groups. They look good, are unobtrusive and have a nice backlight. In general, I like Flex. Perhaps my favorite feature is the silent alarm. In the morning it is sooooo nice to be woken up by a gentle vibration on your wrist instead of an alarm clock ringing! But the bracelets themselves pick up color from clothing as if it's no one's business. Never wear them with long sleeves that have never been washed. Depending on the item, do not wear them with a garment that has not been washed 10 times! Okay, maybe I'm exaggerating, but I have a sports jacket that has ruined three stripes even though it's been washed. I went through the two original straps that came with the flex ring, then bought a set of different elastics and kept one for myself and gave the other two to my daughter, the one I kept is dirty now. I've tried putting them in the washing machine with the laundry but the stains won't wash out. I thought dishwasher safe but am not sure if the material is dishwasher safe. But to date, nothing has settled these things. That wouldn't be a problem if they were cheaper. I will now wear the dark stripe until warmer weather comes so I don't interfere with my flexibility with long sleeves.
