Move+ Pro Extender Strap - Pair with the MOVE+ Pro LED Device - Enhanced Compatibility - Portable Design - Seamless Integration - For Extra Circumference - Ideal for the Back, Hip or Stomach

This strap is expensive, hard to adjust, and hard to use. Inexplicably, there is also a huge pad on the front with an equally large and outward facing logo turning you into a walking billboard. On the up-side, amazon made this easy to return...Do not buy this product. If you want to try kineon on your back, buy a 1" elastic band, some snap clips, and repurpose the clips from yout knee strap to hold the lights. Not perfect, but for ~$5 you will have something that works better and is easier to adjust.

..... that I could have used....I suppose it works fine.adjusting it, like the main straps of the Move+pro is a pain the butt though. Seems like there has to be an easier way?I have zero confidence in those plastic connectors though. I give them 6months, a year tops before one of them breaks.
