I regret to have sincere this device ever praised. I have this filter naturally receive in new condition and found to be impeccable. Rightly so, because it was in this state also still perfectly. It is now seven months old, and it now consists of three parts! In this state, it is of course useless, I withdraw my recommendation to buy back hereby.
If anyone should have bought a result of my review, and has made similar bad experiences - forgive me, but I could not foresee that!
