There are no metal pieces, which can trigger allergies in certain people, therefore I ordered four of these to give to my whole family. In addition, moisture protection is extremely helpful and should not be removed if water is present. Well, good thing there's sleep tracking since I figured out my sleep pattern and now I'm sleeping well. It's not a terrible counter, but it's not great either. The pulse is spot-on. The fitness bracelet was well worth the $16.90 I spent on it from an online retailer.
