As a software developer and gamer, I use Klutch1 not only to prevent sweat but to reduce oil build up on my mouse and keyboard. It helps prevent build up and reduces the need to clean oily keys over time as often as before. Not only that but it keeps my hands feeling natural and with the right amount of grip to where I feel no slip when using my keys and mouse. In addition, I use Klutch1 when using my controllers, steam deck and Nintendo switch. I also use it to have a better grip when handling basic tools like hammer & nails, power drills, screw drivers etc. It's a very useful product and I recommend it to everyone and anyone who can benefit from it the same way I have.
