“Works well BUT honestly works a little to well! DO NOT leave in with your material for more than an hour or 2! I left mine in over night and it was way to long! Almost ruined all of my stuff and it was a chore to try and salvage it and dry it back out. There should definitely be some kind of warning or disclaimer that comes with these because you will over hydrate if you don't know what you're doing. Use with caution!”
