I've had a lot of problems with the stock neoprene straps on my Fitbit. No matter how much I cleaned them, changed them, or immediately removed sweat, I would end up with terrible rashes. I was skeptical about these. However, they are comfortable, breathable and durable. I've been using it since January. I didn't have any rashes. I wear mine all the time. I take it before the shower. I haven't had any issues with wear or discoloration. I am very happy with it and will buy more.
