Tested at 440' - all the space I had at the time. Worked great in all three modes. I really like the ability to buy multiple units and use one remote to operate up to 6 individual or 6 groups of units. The system really allows lots of room for expansion and best of all it works! The only negative is the directions are very sparse. A little investigating and it was pretty easy to figure out though. I bought one to start and plan to add at least 3 more.

I loved this small system. At the beginning, I lost the directions on how to program it, but after sending an email to the site, they happily gave me another copy. When I got it all set up and programed, I was amazed at how good it worked. I thought since it was small, it would have a bad signal, but it didn't. I tested it from as far as I could go and it still worked, even though all the houses and trees. Altogether, a great buy.I will be buying more in the near future to make my shows bigger and better.
