Professionally (like quality items should be). I was a little disappointed that I needed to go online to find user instructions (it is NOT included). Just go to fitbit.com and select your fitbit model and look for users manual. The instructions are pretty straight forward.
The "Blaze" wears great and the functions are pretty amazing. I would buy from this seller again and I do recommend the FITBIT Blaze.

Absolutely in love with this smart watch. It was an early gift I gave my boyfriend and he loves it as well! It has great features and helps you monitor your health. You can track your sleep, steps, workouts, calories burned and so much more! Although it is meant to be used when you're working out, you can use this watch on a regular basis even when you have to look professional; just by simply changing the band, you can make it look like a fancier watch.

Stopped working/charging 30 days after my purchase and this was our second one. The first one didn't last 30 days either. We thought that one had a defect so we returned it, but turns out this one didn't last much longer before its no good. I am so disappointed because My husband and I both loved our fit bits. I have a Charger 2 and have not had any problems at all with this model. It was promptly replaced with a new one and my husband and I still love out FitBit!

I love this tracker! I have had it for six months now and use it every day. The charge lasts four to five days, depending on what I am using it for. I love the fact that my texts and calls come through - esp when my young girls are playing my phone. I can tell them if I need to answer it or not without having to look at my phone! My wife and two of our kids have the Charge 2 which is also very nice, but I prefer my Blaze!

I was a little hesitant about purchasing any Fitbit after initially ordering the Charge 2. After receiving it in the mail, I immediately removed it from the box and attempted to set it up. I soon became frustrated and disappointed that it wouldn't connect to any Bluetooth equipment that I own. I tried everything that was suggested on the Fitbit website as well as what other people who had difficulty and nothing worked. I'm thinking it was just a fluke, idk. I decided to return it and contemplated as to what kind of tracker I wanted. I even looked into the Apple watch. After reading the reviews for the Blaze and seeing that the majority had a lot of good things to say about it I decided to give it a try. Plus the price was right after it went on sale for Black Friday:)
Well, I can honestly say, I had no problems whatsoever with the Blaze. I absolutely love it and all the wonderful things it can do for me. I can also agree as others have mentioned in their reviews, that its pretty accurate on tracking heart rate and steps. The app for it is a nice feature and is very helpful whether your tracking exercise/activities, sleep patterns or your heart rate. It's exactly what I wanted in a tracker and it looks nice also. I recommend for others to give it a try too.
