Title: Great Pet Door
Review: I have had one of these installed for several years. I got the cat one first, and when it quit working a few years later, I installed the bigger doggie version. My pets can get in, but neighborhood pets can't. It uses a 9 volt battery, which seems to last for about a year. The pets don't mind wearing the magnets on their collars. I keep mine set so that they can get in, but can't get back out. They will sometimes paw at it trying to get out and they knock the battery compartment door off. Intermittently the magnet does not engage the locking mechanism - I think the solenoid may be a bit flaky. Overall, this door is well worth the expense of buying and installing, even with the intermittent flakyness.
