    • Had a Fitbit “forever”
Color: Carbon/Graphite
I was an early adopter of Fitbit back when it was just a little clip thing- the company then was small and had really great customer service, they’d send a new little device if the one you had stopped working. While I’m sure the company is now very different Ive still always had a Fitbit of some kind, I appreciate that Ive had my health data compiled since 2010! This device has been great, I love the smart watches that also track my sleep and vibrate to wake me up, and remind me to get up and move around every hour. The bonus of getting text messages on my watch, seeing calendar reminders pop up, check the weather, etc has been great. I’ll always be a Fitbit customer. ... show more

    • Great battery life, love the bright easy to read screen
Color: Carbon/Graphite
I am a long time Fitbit user. I upgraded from the Fitbit Charge 3 because I couldn't read the Charge 3 screen at all in the sunlight. The Fitbit Sense is easy to read even when it's sunny out. Great battery life & charges super fast. Sleep mode is very helpful. I really wish that you could fully read text messages & emails on the Sense. Also wish you could see your full reply when responding to someone via voice to text. Sense isn't useful/helpful when you have to use your phone to see full text messages, emails or your voice response to make sure there aren't any wrong words in your voice to text before sending. The purpose of those features are so you wouldn't have to rely on using your phone. Also, sometimes when you press on a notification Sense will occasionally clear other unopened notifications. It doesn't happen often but is frustrating when it does. In exercise mode I wish there was an option to see the current time in addition to elapsed time, distance, pace & heartrate all on the same screen. It would be helpful when doing 5k races or training for a race. I do like the current option of seeing those on separate screens too but would prefer the ease of seeing all on one screen. Golf mode has shut itself off a few times when I've used it. That's disappointing when you're trying to keep track of total play time & total steps specifically during the hours of playing golf. Wish I could get the "Golfpad" app on my Sense then I could use my Sense instead of the app on my phone. Also wish there were more free clocks similar to Spectrum that showed current time, date, steps, sleep & heartrate on one screen with a nice picture background that was easy to read. Overall I love the Fitbit Sense. I plan to try more of the other features such as music soon & hope I can listen while keeping the walking exercise mode running during a race without a problem. Hopefully I'll be able to switch back & forth quickly & easily. I bought the screen protector for my Sense & have been using it since. So glad I did as it's protected the screen many times from being bumped or accidentally dropped when trying to put it on. Wish Fitbit would sell the screen protectors. Would also like more color options for the sport bands including an all black band and breathing holes. The sport bands & Sense are very comfortable to wear even while sleeping. I recommend the sport brands if you play a lot of sports or are very active to ensure it stays on. I love the square face of the Sense. It's large enough & bright enough to read indoors & outdoors yet delicate looking for a small wrist. One last thing, wish Fitbit gave a better way to sign up for the extra extended coverage. The option popped up on the app on my phone but unfortunately while I was at work & didn't have the credit card on me I would have used to pay for the coverage. So unfortunately I didn't get a chance to sign up for that. The Sense is rather pricey so worth waiting until it's on sale. ... show more

    • Great watch with a few nitpicks
Color: Carbon/Graphite
So first off let me just start by saying the watch itself is great. Does it’s job fantastically and I have no issues with it. However I did knock off one star for one glaring issue and one secondary issue as follows: The stock watch band, mine failed after a month of use, for the price I would have assumed the quality would have been much better. On top of the poor quality the band caused a skin reaction if worn too long, which was pretty much the point of a watch you wear to sleep and throughout the day. That could be a personal allergy but still a concern. Regardless I don’t think the band should have been pulling apart 1 month into use. I have since ordered alternative bands to replace to original. My second and more minor issue is that the watch doesn’t take much rough use to get damaged. I managed to scuff a small mark on the screen a couple weeks in and ordered protective covers immediately. Yet again, at the price point of a watch marketed to fitness, one month in and I’ve now replaced the band due to poor quality as well as covered the exterior of the watch hiding the rather nice look due to concerns of damage. None of this is major, however it should be noted for anyone looking to purchase that there can be other costs involved on top of the cost of the watch itself just to keep it in good shape and wearable. I stand by the 4 stars, the watch functions and app are both fantastic and easy to use and I love it, just wish it had a few quality of life improvements on the parts that hold it all together ... show more

    • Love the weekly review
Color: Carbon/Graphite
It synchs with my Weight Watchers app. It shows me my progress for the week so I can focus on where I can improve. It lets me drill down and get a more precise look. Especially walking and weight. I’ve had a Fitbit forever. It has a square face not round. Love Everything!!!😊
