Look nice and keep your wrist dry.
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.

Better airflow
I was having issues with getting rashes under the original bands because water and soap kept getting under the original bands. Well, that hasn't happened since I got these new bands. Switching them out is super easy, it's just a little lever and they're magnetic so they click right in. I also like that the band has a more traditional watch band style - both the clasp and the hold down thing instead of tucking under the band like the original Fitbit ones. I think it is more comfortable for day to day wear though I understand why Fitbit thought the smoother profile would be better for super active people. I'm not doing hardcore sports so the more traditional watch clasps are better. I am very happy with these and I would buy them again.

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....

Works like a charm - a little short if you have big wrists.
Listen, I love Whoop...LOVE. But, purchasing replacement bands at about $50 a piece is for the birds. I needed a new one since my old one developed a stank and this was perfect. It is slightly shorter than the Whoop brand ones, so if you are thick wristed you should be aware of this. I have a fairly small wrist and don't have a ton of wiggle room on the length. Also, the battery pack is a little more snug than the Whoop brand strap. All that being said...these things don't bother me one bit for the price point!

Better than the band that came with the watch.
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.

I love these bands - the turquoise really pops
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.

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

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.

Good fit discoloured quickly
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!
