Have used about 1 1/2 years to Florabest distribution. Ok, it is a cheap product, but after a few weeks, he has begun to drop. I then always the tap turned off, but that's not the point of it. The idea is good, but by cheapest plastic implementing unfortunately miserable. If one missile? Always nice to Hahn, he is available. When the but does not want to, then you should spend a few more Euros. Function well (hence 2 stars), but unfortunately leak quickly.
