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.
Apple Watch Series 3 Space Gray Aluminum Case with Black Sport Band
  • Great product. Bought it for my husband to track his activities and he loves it!
  • Fantastic watch, apple products are always a good buy. It synced with my iPhone 7 and I can play my playlist of music without the phone nearby, all I can say is WOW!!!
  • My wife loves the watch and the ability to easily change the bands to match her clothing. Great gift!!
  • Greatest watch ever! You don’t have to have your cell phone near you anymore. Love the Velcro watch band. Secured but easy off and on.
  • I've been an Apple consumer for over 7 years and I really like their operating system. I currently own an iPhone 7+and now the series 3 watch. I love it!
  • My only complaint is in the operating system. I’d like more control over the appearance of my watch face and complications.

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.
Apple Watch Series 3 Space Gray Aluminum Case with Black Sport Band
  • Display is crisp, functionality is good, fun to wear
  • The Apple watch is an amazing device. And the display is gorgeous.
  • My wife loves it. She preferred the smaller one over the larger display.
  • Quick touch response, bright display, offers a ton of configuration options, improvement on previous version
  • Upgrade from my sons Fitbit. He seems to really enjoy the features and display with this Apple Watch.

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.
Apple Watch Series 3 Space Gray Aluminum Case with Black Sport Band
  • Love the watch. I just wish they sold round faces and not just squared.
  • Love my watch. It is easy to use. I love the Toy Story face!!
  • Love my Apple Watch. Not use to having my wrist vibrate all the time.
  • Love my new Apple Watch first one ever! Works great only downfall every now and then you can feel it vibrate against your wrist for no apparent reason.
  • Not happy with protective shield purchased with it
  • I would recommend getting a protective case for the watch bc it scratches easily.

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.
Apple Watch Series 3 Space Gray Aluminum Case with Black Sport Band
