They are great but as many others have mentioned its a bit cumbersome and cleanup can be annoying. I pretty much exclusively use it in the shower out of convenience because of those reasons. I can wash up immediately after and clean out the sleeve as well. Then dry and put everything away. That being said try to leave at least the back cap off before storing so it can really get good and dry cause you definitely don’t want any trapped moisture in there just stewing. I did end up getting their little spray cleaner thing but you can just use soap as long as its not oil based as it can break down the material. Pretty sure there’s a guide online how to just make your own spray solution as well so you can save a couple bucks.
