Title: Magnets break
Review: You have to have this product if you have the door. Unfortunately, the casing for the magnet breaks about every 3-6 months. I have 2 cats and had the door for 3 years. We've gone through about 10 collars. It's pretty annoying, but I guess this is how the manufacturer keeps us buying their product. We have no choice.I love the door, great concept. Just annoyed that I have to keep buying collars.Amazon has the best price I've seen. Don't go directly to the manufacturer. They're pricey.
