Bests & Worsts Reviews from Amazon

While this is a really cool little band, the clasp is just ridiculously complex and hard to secure. While other bands and watches have clasps that you press down or they stretch or have a buckle, this product went for the "slide one end through the hoop and then slide the clasp in SIDEWAYS to secure it. This might work fine with a small wrist, but with a large wrist it's almost impossible to secure because the loop gets in the way. The fact that you have to take it off to shower means you'd be wrestling with the clasp on a daily basis. Really, a terrible design flaw. The Jawbone often does not react to being tapped twice. You pretty much have to use the app to change modes since double tapping simply doesn't work, or doesn't work consistently enough to be a useful feature. I'll use it a few days, but I'm pretty sure I'll be returning it. The whole band/clasp system is a disaster as you can see from the photo. Edit: I found that if I just tapped the top of the band 10-12 times, that usually wakes the unit, but double tapping never works. I tried the sleep tracker last night and it told me I slept 45 minutes in 8 hours, so this product is completely useless to me and I'll be returning it today. Lowering the star rating from 2 to 1. I won't give better than a 1 star review for a product that is defective. I've checked on the web and there are many complaints on this item.
