Overall good, but has issues
Amending review below, to drop to 3 stars.  It only measured sleep the first night and hasn't measured it since then.  The band really chafes my ankle, so I have to keep adjusting the tightness and location of the fitbit.  That aside, it's a nicely made ankle band.  If you don't want to measure your sleep and don't mind the time it takes to insert/remove the Alta for charging, it's a great band to have.<br /><br />The good:  once the strap is attached it's reasonably comfortable (don't strap it too tight to ankle) and it does work with counting steps accurately.  A bonus is it can be worn to bed and will track sleep (some ankle straps say they don't track sleep, but this one does).  The straps are really nice looking.  The not so good: the pocket for the Alta is SO small it took about 10 minutes to get it inserted.  Although nice not to have to remove it each night for sleep tracking, that means it takes 5 minutes or so to remove it to charge the Alta since it can't be charged inside the strap.  Then count on another 10 minutes to get it back into the pouch.  Even with only charging the Alta every few days, that's a lot of time spent trying to get the Fitbit in and out of the strap's pouch.  The other thing to be careful of is the strap is flexible so I need to look down every now and then to ensure the strap hasn't turned inside out and the Fitbit is facing out rather than next to the ankle.  Tightness doesn't remove the problem and you'll need the looseness for comfort.
