Bests & Worsts Reviews from Amazon

This is great, until you actually screw it on. Then you realize the bean counters at Delta Faucet skimped on the design and instead of using a normal slip collar to attach it to the pipe, they used a FAUX COLLAR. What this means is that if your threading does not precisely line up with theirs, it will *not be straight when tightened*. See the video...it's a terrible design. The best solution is to keep it from leaking is to use way more teflon tape than you should...or better yet, never buy it to begin with!
