Not bad for the price, but then it started leaking after a couple of months. I took the valve apart and found one of the two o-rings was cut most of the way through. Replaced both o-rings with these:50 Pcs Flexible Nitrile Rubber O Rings Washers Grommets 4mm x 9mm x 2.5mmand it works fine again.<br /><br />Bonus: Used the rest of the o-rings to quiet down my Corsair K70 keyboard!
