For $30 I can't complain about the way it works. It counts my steps and it syncs with the apps information. HOWEVER the app is very outdated when it comes to the food logging. I have to use my fitness pal and sync the two apps together. It doesn't automatically sync with the band either, it takes a few minutes sometimes and then other times it doesn't. Sometimes when you tap the band to see what mode you're on it works and sometimes it doesn't. If you don't go in to the app every night and put it on sleep mode it won't track your sleep , I've found that some morning I click the button and then I wake up and it has shut off and didn't track my sleep. Worst part about the band itself is if you get a light color or anything other than black , and dirt or other things that come in contact with the ban stain it badly. I got beige and it's a greenish yellow color now. Had grey marks all over it that won't clean off from being rubbed against things.
