Product review (5 stars): OEM Product - easy to change
This is the OEM Product and it is easy to change, Just pit a sponge under where it comes out in case you drop a little water. Maybe 1 or 2 drops. Then go into the menu and reset the counter to another 6 months. Really EASY to do, Even a child can change this. Really good design. Comes with a very small instruction sheets because it is really simple..
