What customers say about "Key Specs"
Fitbit Blaze Smart Fitness Watch
  • I cannot say enough about this product. I really love it. The entire "system" of the band + blaze is very comfortable.
  • I have had it for nearly a year now and am still pleased with it. it charges fine, and operates great.
  • A great deal of thought went into the product design both in capabilities and ease of operation.
  • The band is somewhat uncomfortable, especially to sleep in. The buckle digs into my wrist on the side. I would like to see someone come up with a buckleless, soft silicone band like the apple watch.
  • Plastic wristband gets sweaty and, if you wear it day after day, can cause some skin redness in places. I recommend washing the band in soap and water daily, and taking it off for a little while each day.
Fitbit Surge Tangerine, Small (US Version)
  • Generally good. Covered a lot of activities (but not some I thought it should, like swimming). Ease of use and nice APP.
  • All in one device. If you really want a fitness tracker, sleep tracker, HR device, and a GPS run watch this is your best bet.
  • It looks pretty good, I have heard that the pulse meters on devices like these are not too accurate, but when comparing it to manually taking pulse and with a pulse-oximeter machine they are pretty close.
  • Very comfortable band. I haven't had any irritations but I don't wear it too tight and frequently give my wrist a break.
  • The band on the Fitbit Surge is poorly designed and constructed. It causes a severe rash / damage to the skin underneath it.
  • No GPS calibration of accelerameter ala TomTom and Garmin. So if you do run indoors with this thing do not expect anything more reliable than a garden variety fitness tracker.

What customers say about "Display"
Fitbit Blaze Smart Fitness Watch
  • Large screen, easy to read display
  • The large display is most helpful when you want to view your progress or view an incoming notification during a workout without having to pause.
  • No fancy technology on the screen used. From the specs it looks like a low quality screen, I will not disagree, the pixel that made up the digits can be easily seen when watch is put closer to the eyes.
  • I love the display so I don't have to go to my iphone to look at numbers (like I had to do with my Fitbit One).
  • My only complaints were a lack of more choices on screen display options or configurations and colors.
Fitbit Surge Tangerine, Small (US Version)
  • I especially like that it's simple to set up, that I can read the display without having to wear my glasses, and that it's easy to use.
  • Beautiful and easy display. I think it just looks attractive
  • Also, I find the display hard to read, very dim with poor contrast. I don't have great eyes anymore at 50 years old. So basically this is useless for my purposes, and I do not recommend it at all.
  • I would love to see the screen have the option to default back to the time screen. It currently stays on whichever screen you last viewed, so sometimes that is frustrating, but nothing insurmountable.
  • I have had my surge for less than 2 weeks and its already glitching all over the place. The screen keeps blanking, or showing up in small portions.

What customers say about "Features"
Fitbit Blaze Smart Fitness Watch
  • The functionality of the blaze is amazing. Tracks lots of different exercises. The pedometer seems accurate. When I compared it to the pedometers on two other devices they were all fairly close (within 2-3% of each other). I like the text, call, alarm notifications.
  • If you're looking for the bells and whistles of a smart watch I can't really speak too much on that right now and will update my review over time. However if you are looking for an affordable and effective 24/7 heart rate based calorie tracking system then this is it!
  • Design, decent price for a smart watch looking fitness tracker, Fitbit app and community systems, nice acreen
  • Nice gorilla glass screen that doesn't get scratched
  • Automatically tracks steps, sleep, workouts, heart rate. All viewable easily on the screen
Fitbit Surge Tangerine, Small (US Version)
  • The Fitbit web dashboard is not terrible, neither is the app. Sure it could use a bit of updating and Google Fit/Apple Health integration would be a wonderful benefit to the customer but it does its job.
  • The different functions are all great; steps, flights, miles, seeing all that during my day.
  • Excellent tool, good quality, lots of useful features, sturdy, strong smart phone app, great motivator, heart rate monitor
  • The heart moniter seems less then accurate at times but the other features outweigh this function for me
  • I wish it was at least waterproof enough for swimming.

What customers say about "Power"
Fitbit Blaze Smart Fitness Watch
  • The battery life is wonderful. I bought the charging stand and charge it every night, but it looks like it would last 3-5 days, depending on use.
  • Great battery life (5-6 days for me so far)
  • The battery consistently lasts a solid 5-6 days, and charging now seems less cumbersome as it did in the first few days. I bought a spare charger and keep one at work and one at my bedside.
  • Like all of the Fitbits I've had, battery memory is dwindling with every charge. I'm almost down to 3 days...I will try syncing less but I've never modified the setting.
  • If the Fitbit's power gets too low, it will also disconnect from my phone and refuse to reconnect once it's charged. Since it won't sync, it doesn't show the correct time, and it won't save my activity data to my phone. That means it fails as a watch and a fitness tracker.
Fitbit Surge Tangerine, Small (US Version)
  • The battery lasts forever and getting email reminders to charge are so helpful. It seems to charge pretty fast.
  • Charging is tricky at best, impossible at worst.
  • Well one year in the band is falling apart and it doesn't hold a charge for more then a day. The charge was great in the beginning, but after a few months it appeared to last less and less.
  • I fully charged it on Monday afternoon, and hoping it to last to Monday, so that I will only charge it weekly. On Friday day night it starts showing low battery and totally died on Sunday morning. Total 6 days.
  • The charging cable connection on the back is not an automatic connection, requires fiddling.
