I have several of these and use them for many different activities. I use these with a couple of extenders. They are very reliable, have good range. I often use one on my downstairs deck in the back that controls my receiver and computer (where I store my music) located in the front of the house upstairs. This unit is relatively easy to use and very easy to program. The ONLY drawback, when compared to my SONY remote, is that the SONY is capable of learning some commands that the Universal cannot. I am hopeful that this will be corrected in the future. Fortunately, when I come across a command it won't learn, I simply use the SONY to learn the command first and then learn the command from the SONY. I prefer the universal over the SONY because it is smaller and easier to understand.One very nice feature is the on-demand background lighting. The backlight can be turned on and off with the press on a large button conveniently located on the side of the unit.
