This looks great but after about six months of careful use, a tiny piece broke off the tab and can't be fixed. It's WAY too expensive for that! And it's hard to operate manually without using an instrument to pry open the closed cap (the seal is quite good, which is great when the tab works). I'll contact Amazon and the manufacturer to see if they'll replace it, but am not hopeful; if they do, I'll update this review. Buyer beware!
