Durable.
I have this case for a couple months now and glad I got it. It is durable. I keep it in the front pocket of my backpack all the time and I'm always wearing my backpack, even when I'm sitting in a chair. So veeery durable. Lol. I'm only giving it four stars because of the bottle, where you put your solution. Whenever I'm making sure it is sealed tightly, it just unscrews itself. So I do it lightly but don't feel like its on all the way. So far though, no leaks. Hopefully the bottle stays like that. Haha.
Rating: 4 stars
