I bought two of these to go either side of our drummer and they replaced four older lights. Programming was really straight forward, although the range of pre-programmed shows is a little limited; same lights going left, followed by same lights going right etc. However, I have also programmed a few static displays and in concert with the other lights they provide a fantastic backdrop for the band. We use them pointing down at around 45 degrees, they are too bright to point towards the audience. Use a bit of smoke and they look amazing. Brilliant features and they are build withstand anything (all metal). I took off one star for features because weirdly there is no spigot in the middle to steady them on a pole so they can wobble a little. The smaller ones in the range do have the spigot, strange that these bigger ones don't. Overall - superb!
