doublevr The issue I’ve experienced with both the Handy 1 and Handy 2 is with the sleeve. Sometimes, the sleeve comes off the sleeve band. This happens because the sleeve can become inflated with air, which reduces sensation. To fix it, I have to squeeze the top of the sleeve to release the air, but that partially deflates it and makes it more likely to slip out of the band.
I think to solve this issue, the lip/flange needs to be bigger and having one side be flat, so it can sit on the sleeve holder. There might be a better solution, iono.
