I'm a nut for outdoor projectors and when I seen this one as a dual, I had to have it. I'm not disappointed at all. Not only do you get the usual pictures but you get the 2nd lamp that gives you a ripple effect. Mixing and matching the colors with the slides provides a great visual experience that is best viewed indoors. You get 12 different slides and 10 water wave colors - enough to decorate with for anytime of the year. This is so much easier for outdoor decorating that I highly recommend it. As long as you have an outlet and an extension cord, you can set this up in a matter of minutes. One other feature this one has that my others don’t is the neck piece that you tighten to keep the projector in place has serrated edges. This locks it in place so that it stays where you want it. Yep, this is cool as heck!
