For the past 4 years, I've been wearing a Fitbit device of some sort. I started with the One, which stuck with me for the better part of 3 years, then I tried theBlaze, the Alta, and theCharge 2. My main complaint with each of these trackers was the lack of water-resistance, which meant that I couldn't wear them in the pool or track my swims with them. I've tried several swim trackers including the Misfit Shine 2 Swim Edition andAmiigo, looking for something that could replace Fitbit, but the best that I found was the Garmin vivoactive, which has excellent swim tracking and can send the main stats to Fitbit through MyFitnessPal. It's not an elegant solution, but it worked for me for the past year or so.
So you can imagine my joy — better yet,you can read it — when Fitbit announced the Flex 2 with water-resistance and swim tracking. At last, I wouldn't have to go through workarounds to get all of my swims to show up in the Fitbit app, and I could keep it on in the shower and the pool without worrying about it.
I've been wearing the Fitbit Flex 2 for the past month or so, and using it exclusively for over two weeks. The result is a little mitigated. Several compromises had to be made with the Flex 2, and that's understandable but only to a certain point. The Flex line is one of the most basic Fitbit models, so you expect it not to come anywhere near the capability of the Alta, Charge, or Blaze line, but in some respects, the Flex 2 even feels like a step back from my 4 year-old Fitbit One, which is slightly disheartening.
Tiny and light The new Flex 2 tracker is so small and light that I can barely feel it on my wrist. Band The band's clasp is solid and never even one popped off or came close to it. The band is also removable so you can buy new colors, a bangle or even a pendant. Oh and the Flex 2 ships with a regular and a large band in the box - no more worrying about which size works best for you. Water resistance and swim tracking The Flex 2 is shower-friendly and water-resistant up to 50m. This is the first Fitbit to have that rating. And swim tracking is automatic without fiddling with your phone or tracker. Automatic sleep tracking and exercise recognition Like all recent Fitbits, the Flex 2 can automatically log sleep, recognize which exercise you were doing, and track it. Even swims. Reminders to move It's one of the cheapest Fitbit trackers that can vibrate to remind you to get off the chair. Better tracking with your phone The Flex 2 doesn't have GPS built-in, but it can use your phone to launch a manual exercise log with GPS route tracking. The Not So Good
No official clip Fitbit doesn't sell an official clip for the Flex 2. I'd love to wear it on my pants or bra, because I often walk without moving my hands (treadmill, holding phone/tablet, hand in pocket...). No stairs tracking There's no altimeter in the Flex 2 so it can't track how many floors you've climbed. Even the Fitbit One can track flights of stairs. LED lights instead of display The LED lights are adequate, but there's no way to tell the time, see the exact number of steps, or get proper notifications through them. Another proprietary cable Yet again, Fitbit decides to create a new charging cable design that no other tracker uses. Swim stats No stroke or speed stats, no interval recognition, no SWOLF score, the current swim stats are based on calorie expenditure and very basic compared to what other trackers provide. Price At $99, the Flex 2 feels a bit overpriced given the lack of a real display and altimeter. $79 would have been more realistic. The Flex 2 ships in Fitbit's signature box with the tracker, two bands to fit regular and large wrist sizes, and the charging cable. The Flex 2 tracker is so small and light that the first time you see it, you'll probably be very surprised. There isn't much to its design: the front is a glossy black that hides the 5 LED lights and the back has the regulatory certifications and charging pins. The front is also touch sensitive: you double tap it to see how far along you are in your daily goal. The 4 white LEDs light up to tell you when you've reached 25, 50, 75, and 100% of your goal.
