Product review (1 stars): Excellent - later revised to Not So Great
Bought this 2 years ago b/c we couldn't use a magnetic one. Recently, the adhesive wore down (I'm guessing) and it fell off during use. But, I'm buying another one! Sometimes it's a little difficult to slide the piece into place, but it is effective and lasted a good time given the price.

Revised: Replacement only lasted two weeks. Disappointing.
