    • Tons of capabilities for small product!
Color: Black (Heart Rate) Size: One Size
Love this product. I’ve had multiple iterations over time and Fitbit keeps advancing capabilities. This version syncs with your phone for texts and has really good ‘exercise’ tracking (proactively pushing options to ‘start a workout’. Kind of similar to Orange Theory, this Fitbit tracks in a certain fat loss zone. None of these capabilities did I expect from this version. I just lost an older version and purchased the more modern option and have been happily surprised. Battery life lasts for weeks! I go at least 3+ weeks between charging, and full charge takes an hour or two. Impressive and highly recommend. ... show more

I like the product itself, but after having 3 die just shortly after a year (just outside the warranty period), I can no longer support this product. They should last several years, not barely one. Google it - many people experience the same thing. The products are not good quality if they die in about 13-14 months. ... show more

Color: Black (Heart Rate) Size: One Size
I like the fit bit. The only issue I have, is that I have to charge it every week. when I had my fit bit one, I only needed to charge it every 2-3 weeks. sometimes my calender alerts continually go off on my fit bit...not sure why?? Otherwise I think it works great, I like that it measures my heartbeat and my levels of sleep without having to tell it I'm sleeping! I like that I can get alerts to my messages and phone calls on the band itself! This way I don't feel the need to have my phone on me 24/7! ... show more

    • I love this product!
Color: Black (Heart Rate) Size: One Size
I upgraded this from the basic Fitbit flex two and I’ve been very pleased with it. I’ve been comparing the heart rate with my Apple Watch as well as a heart rate monitor for my spin bike in there that’s far very accurate. Calorie burn is a little on the low side but that’s no biggie. Also the step accuracy is point on.. The only thing I really wish the app would allow me to do is to enter in my workouts. I do a lot of weight training and the app does not have this as a category-Also the calorie estimations are extremely low Other than that I really like the Fitbit. It’s durable and I also really enjoyed the sleep analysis feature (although I think it’s a little price! $9.99/mo!) ... show more
