Fitbit Charge 4 Fitness and Activity Tracker with Built-in GPS, Heart Rate, Sleep & Swim Tracking, Black/Black, One Size (S & L Bands Included)

I was diagnosed with afib. This permits me constant status of my heart rate. The band wears out about once a year so I keep a replacement on hand. After about five years the connection on the watch to the band broke and I needed a new one.

I'll never buy another fitbit product. I purchased my 2nd fitbit after the first one broke (plastic where the band clips to broke). The first one I had awhile so I picked up another one, no big deal. The 2md one lasted 2 months. During the day the fave wouldn't light up. Per the app it was still tracking my steps. When I got home and threw it on the charger it wouldn't take a charge. Onto customer service. I went threw the app and called them. Answered all the questions and completed all the requests. They said I would get an email. The email I got was that it's not under warranty. And just like that I was out of luck and they haven't responded to any other emails from me.

I absolutely love Fitbit Charge 4. Just the right size for me. This is a great buy, but I'm having to replace this refurbished one and will purchase a brand new one. It's very easy to use. Now you have to pair with a Google account. The sleep information is very helpful

This is my second Charge 4 Fitbit and I really like it. I can track my fitness, my heartrate as well as my sleep the list goes on. This new one fits quite well. The band was kind of small for my hand, so I fit a little larger band on that I had from my old Fitbit. The setup was quite straight forward. You have to upload the App onto your phone then sync the watch to your phone. Patience is needed with the setup, it takes a little while. It also takes a while to charge the watch initially. So far I am happy with this new watch.

This is a replacement. Hubby wanted the same kind he has for a few years. But we are having a difficult time to get it synced with his phone. Since we did not purchase it at our phone store they will not help us.

Only lasted 1 month before the light is so dim it can’t be read in daytime. This is my fourth day ne in about 2 years. I won’t order another one.

Works like a champ. Easy set up and easily read displays.

Has the same problem as other fitbits, the band will break at the watch and is unrepairable. Lucky there's a solution with different bands where you can just put them in the holder of the band and not have to attach the band with hardware. It's a good exercise watch, but that weakness is a major issue for something so expensive. I'll go with something else whenever this one dies.

This is my 3rd Fitbit Charge 4. To my mind, it's the best one that the cimpany has made. At least for my purposes: hrs of sleep - this still needs to be adjusted, it starts my sleep around 3 am almost every morning and so I have to remember to write what time I'm going to sleep to correct it later. Other functions suit me fine.

Primera y última vez que compro un producto de segunda mano. A pesar de la garantia de Amazon de que se ve como nuevo. Se descompuso al siguiente día. Solo una pérdida de tiempo y esfuerzo en devolver el producto. Me gustaba mucho ese diseño y ya no es posible encontrar el fitbit nuevo

Electronically, the watch works. However within a month the strap has broken. The connections that are usually on the middle section have come off and I can no longer connect the strap to the watch..

Detective worked initially. Attempted to charge a second time. Smelt melted plastic and found the watch and charger fused together. FIRE HAZARD!! 🔥 This is my second fitbit. The first one I had with no issues for over 5 years

Sa fait 2 fois je l'achète ( la première ses brisé 2 ans plus tard) J'aime beaucoup cette montre intelligente.
