When used in conjunction with a new water filter i no longer have to replace my Brita when we change filters. Very easy and fast to get the water flowing. You can switch them out more then once.

Good Review

Excellent product, easy to read without glasses, works on every type of battery and does not require any additional power source other than batteries. I use it with a small LED flashlight for all kinds of things including checking my golf swing. The LED is much stronger then the old flashlight. A plus is that I can clip this device anywhere in place which makes clipping or removing your shoes even easier. If you need a great reliable wireless device, get this.
