I received this as a gift from a family member. I think that it is a bit pricier than I would personally spend; I probably wouldn't buy one with my own money. I received three coloured bands: black, gray-blue, and red. I don't like the little pegs that you push through the holes to secure the bands on your wrist. It is nice that you can adjust it, but compared to my old Microsoft Band and for the cost of the Fitbit, I think they could've made that part better. The band, once adjusted properly, is comfortable on my wrist. Sometimes I forget that its there because I hardly feel it. It is at least water resistant, because I forgot to take it off several times while doing the dishes, it has been exposed to the rain, and once it partially fell in a puddle when I was adjusting the strap while outdoors; so far it hasn't had any adverse reactions to a tiny bit of water.
Otherwise, though, the battery charges pretty quickly, and lasts for quite some time. I have an Android phone, and the app notifies me when I need to charge the battery. The charger is a short USB cable type, and is easy to use as it is shaped very specifically. I wish this version had a little screen that displays the time. The app is very useful, and syncs pretty easily with my Fitbit. I like that I can add friends and cheer them on or participate in challenges/contests. I also really enjoy that it has a food, water, and sleep log. I enjoy having a steps goal set, and always look forward to feeling the vibration on my wrist and seeing the lights flash to indicate that I met my goal. Its also nice that the app tracks exercise. Overall I like this product, though I think for the cost there could be a few more features.
