What customers say about "Key Specs"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • Apps that are available are actually pretty good! Doesn't include everything though.
  • They're really good at building fitness tracking hardware, and developing an incredibly solid app interface. Expanding to building a full operating system and managing an app store just seems like a bad move.
  • The current (rollout) features are very good, and I only expect them to get better as the system matures.
  • The band is quite stiff though but perhaps I have to break it in.
  • I also like that Fitbit included two different sizes of watch bands instead of wasting everybody's time measuring their wrists.
Samsung Gear S3 Frontier Smartwatch
  • So far this watch has been great, love the design and features that it has. All and all a great watch.
  • The frontier s3 feels like a luxury watch and looks like one while being able to do so much more.
  • This is a great product. It has a lot of functionality for everyday life.
  • First one had a charging issue but easily exchanged. New one shows no problem so far and I love the design and performance.
  • Nice band for my watch, also purchased the screen protectors for it makes me feel safer to know that my watch is protected. Overall I am quite satisfied with my purchase.

What customers say about "Display"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • The display is easy to read while running and you can customize the displayed stats.
  • The screen display is bright and sensitive, and the watch itself was extremely intuitive to setup.
  • I switched from my old Fitbit Surge to the new Ionic and I absolutely love it! I find the display so much easier to read.
  • Screen saver timeout is not currently adjustable and only stays on for 2-3 seconds.
  • Only "run" activities are displayed in the Strava app on the Ionic. I do other activities too, it would be nice if they were displayed as well.
Samsung Gear S3 Frontier Smartwatch
  • Great looking display, very bright & it's great to be able to change the faces.
  • I liked the round face and the color display is awesome. I got home and started setting it up but came to find out that I wasn't Able to reply to text either.
  • Love the display, easy to use, pairs with phone in seconds!
  • Love this smart watch. It has an amazing vibrant display!
  • Still learning but I love it great display just amazing.

What customers say about "Features"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • Automatic sleep tracking - and, it can shut off notifications once sleep is detected.
  • Sleep tracking is pretty good! Definitely better than an app you can get on Apple/Android watch.
  • The features are easy to use and access, A few trial and error and you will get how it works. Often use functions are just a few tabs away. You will familiar with it almost instantly.
  • Slow performance from time to time.
  • Can't connect to WiFi, any WiFi, Home, work, with or without password. Any firmware update needs to be done over Bluetooth and it takes 30 minutes to 1 hour. It is ridiculous.
Samsung Gear S3 Frontier Smartwatch
  • Excellent the sensors to detect the different activities like running, moving, or sleeping.
  • I really like the features on the Samsung watch. My Fitbit was nice but it seemed outdated. The auto exercise could activate a little sooner to match the treadmill numbers.
  • Enjoy wearing it daily and using all the many features.
  • The features available pass competitors not only with clarity of picture but also when using watch for phone calls and texts.
  • Nice features able to answer phone calls and texts and biometrics. Much better than the fitbit surge.

What customers say about "Power"
Fitbit Ionic Charcoal/Smoke Gray, One Size (S & L Bands Included)
  • Great battery life (4 days), very fast battery charging, reasonably accurate GPS, monitors your sleep, you can easily swap out third party watch bands, and recognizes when you go up stairs.
  • Long battery life - I made it from Tuesday to Saturday before it needed a charge.
  • Excellent battery life. Without GPS tracking, I left everything enabled and still charge every 6 days. All notifications are active.
  • In terms of battery life, it seems on par with my Blaze. Today is day 4 of owning the Ionic and it is still on the initial charge it came with (with notifications off).
  • I have a nice, convenient metal surface where I can stick the charger for easy retrieval.
Samsung Gear S3 Frontier Smartwatch
  • Great that it can hold a charge for almost 3 days were others can only last 1 or 2 days.
  • Very good on battery usage. Once it is charged to 100% it status charged for at least 2 days!
  • The battery life is good, charges very fast too.
  • Husband loves it. The charge time is awesome and it runs smoothly.
  • After about three weeks the watch failed to charge. I touched it and it was hot to touch. I returned it and got a Garmin.
  • I like the watch, but it needs charged more then my Fitbit blaze did.
