Customers say
Customers find the watch band better than the factory version, with great color options and good value. The band is comfortable, with one customer noting the holes help with heat, and they like its appearance. However, the fit and durability receive mixed feedback – while some say it fits well and lasts a while, others report it doesn't work with their Whoop device and breaks easily. The clasp and appearance also get mixed reviews, with some loving the look while others find it terrible.

Over the years I’ve been using Fitbit, I’ve found their OEM bands suck so I always buy bands off Amazon to have on hand. They usually last longer than the originals. When my charge 6 arrived. I had the backup bands ready to go. I didn’t like the original bands at all, so I didn’t even bother putting it on. Switched out the band with one of these and it’s great. It’s actually my favorite after market band for Fitbit I’ve ever used, very comfortable.
These bands have proven to be durable and don't irritate my skin because of the breathable design. They aren't flimsy, they are just the right thickness in my opinion. In this batch I love look of the purple and the turquoise. The peach is fine, and I've never been a fan of burgundy. This can fit my 9 year old and it can fit me too.
Fitt my Charge 6 beautifully and snapped on easily. There are other ones available that are three times more expensive but no better looking and probably no more durable….
I really like these bands, and they are easy to change so I can be color coordinated if I want. Price was great, and I'll see about durability as time goes on. I've had mine for several months, and so far I love them!
Less than 1 month after receiving this band, I started getting notifications I’m behind on payment for subscription. I haven’t had a payment on file for WHOOP since originally purchasing years ago and was never auto subscribed since. Coincidence? I think so.
I've ordered two sets of these now and love them. I was having problems with bands that didn't allow air to the skin and these have solved my problem. They are well made, easy to switch out, and the colors are nice.
Updating this to one star from three. I ordered a second bundle of new colors and just like the last package, it is not even close to the same colors. Didn't open this one to test security of the clasps (others I kept have been good) but the color was way off both times. Neither time as vibrant, so keep that in mind if looking for something brighter than black or navy. This latest bundle was to be emerald green and bright teal with a cobalt blue and black. I got black, nearly-black navy, a dark minty green, and denim blue. Only the black was true to the photo. I am pleased with how securely these attach to the Fitbit and the price. The colors are nice, but not what is pictured. I expected a reddish and a purple band, but got two very similar shades that are mix of purple/red/brown. The fit is smooth against my wrist and not bulky, but the tail of the strap doesn't stay held down great by the one loop. Overall, for how cheap the bands were, it's not a bad deal, just don't get your hopes too set on a particular color.

Loved that they are easy to clip onto the bracelet but was very disappointed that they discoloured so quickly. I have been wearing the peach-coloured one for approximately three weeks and it looks dirty and dingy. Oh well! At least it help clear-up the massive burn from the original bracelet!

Works & inexpensive
Fitt my Charge 6 beautifully and snapped on easily. There are other ones available that are three times more expensive but no better looking and probably no more durable….

Colors are great, and the bands are extremely comfortable allowing air to cool the arm.

This band tied to resubscribing?
Less than 1 month after receiving this band, I started getting notifications I’m behind on payment for subscription. I haven’t had a payment on file for WHOOP since originally purchasing years ago and was never auto subscribed since. Coincidence? I think so.
