Review on BSEEN Bracelet Armbands Running Wristbands by Demarco Vonk

I have been using these bracelets (there are 2 pieces) for 2 weeks. I run/walk at 5am PST so of course it's pretty dark. And although the streets are lit, not every crack in the pavement is lit. Sometimes you cannot use the sidewalk and have to share the road with vehicles. Fixed headlights, back/chest etc. do not always give the driver the full picture. These bracelets fit. I have one on each forearm so drivers can see me clearly while driving. When you first put them on, they may slip or even slip a little. After a few minutes of running (in my experience), once you start sweating, you'll hold those bands much better and stop slipping. I've used them daily for 2 weeks Monday to Friday, 1-1 1/2 hours a day and I use the 'hard' setting on both and the batteries have not lost any power let alone died. I am very happy with these bracelets and feel more secure in them.
