In terms of functionality, I have nothing but praise. The restrictor works well, and for refilling it comes out and goes back in perfectly. The cap locks in place securely enough to safely lift the bottle by the cap - which I know, in a wet bathroom, I shouldn't do, but I'm usually shaving before coffee, so not always making smart choices - but opens with ease even with wet hands. The volume is terrific, too, so refills aren't frequent. I'm knocking stars off for the fact that the black paint started stripping off the top of the bottle almost immediately, and the paint strips away a little bit more every week. I'd have been much happier with a clear, uncoated skull bottle than with one with chipping, peeling paint. Doesn't affect the functional utility of the bottle, but it's a big aesthetic demerit for me. Then again, I still have this bad boy perched on my shaving shelf, and it gives me a nice piratical feeling when I use it every morning.
