We have a small fire dept. We needed a few extra remotes for the volunteers. These were inexpensive, and easy to set upEasy to install. Worked as advertised for the price. Little flimsy but I have them mounted on the wall with no issues.Works as described. Garage door goes up and down with a gentle press of the button. Priced right also.Easy to install, stays clipped in placeEasy to link easy to use has great rangeEasy peasyNo tech support required. As I stated, simple,easy, good quality, & great price. What more can you ask: a good tool that does the job at a very good price. I highly recommend.I was able to program two buttons on each remote in less than a minute.
