Review on Firefly Allstar Keychain Compatible Better by Carl Lipschultz

Works great, easy to program and runs nearly 300 feet unimpeded from front door to bottom of driveway. I also bought an Allstar 9931 that didn't work at all and their support team refused to help when I contacted them. Definitely take them with you, you won't be disappointed! Not that it really matters either, but they came in black instead of brown in the photo, which actually looks better. I have an MM600 Estate opener.
