Average Reviews:
(More customer reviews)During the past two months, I've purchased a total of 9 of these red and green laser projectors, from 2 different sellers, through Amazon. Of these, I've returned 4 and kept 5. Based on my experience, there are at least 4 different red and green laser projector types being sold through Amazon. They all look identical on the outside and come in identical packaging, with identical instructions. The 4 types are as follows:
1) The BEST laser projectors project RED LASER laser grids that are 16 or 18 DOTS HIGH and 16 or 18 DOTS WIDE (for a total of 256 or 324 dots) PLUS GREEN LASER grids that are 16 or 18 DOTS HIGH and WIDE. (Since each of these laser dots can have 35 smaller dots converging into it or emerging from it, the total number of dots is much higher. The machines with 18x18 grids are slightly more satisfying than those with 16x16 grids, of course, but I only received one of those in the 9 I purchased.) These individual laser dots are BRIGHT (nearly as bright as a red laser pointer that I own; however, with all machines, the lasers on the outer perimeters of the grid are dimmer than those in the center). The red and green lasers stay on CONTINUOUSLY.
2) The SECOND BEST laser projectors project laser grids that are ONLY 12 RED LASER DOTS HIGH and WIDE (for a total of 144 dots) and ONLY 12 GREEN LASER DOTS HIGH and WIDE. These lasers are BRIGHT and stay on CONTINUOUSLY.
3) The THIRD BEST laser projectors project grids that are ONLY 12 RED LASER DOTS HIGH and WIDE and ONLY 12 GREEN LASER DOTS high and wide. Their lights are BRIGHT, but their GREEN LASERS TURN OFF EVERY 30 SECONDS and then suddenly TURN BACK ON AGAIN EVERY 30 SECONDS. In my opinion, these arbitrary fluctuations in the green laser beams tend to destroy the magical effect of the display.
4) Finally, the WORST laser projectors are DIM, some only about 1/5 as bright as the brightest lasers, and others only about 1/2 as bright.
Overall, these projectors can be a lot of fun, if you can get the best ones, and if you can put up with the hassle of returning the ones that are defective. I recommend buying two and placing them close together, so that the two grids overlap. The brain will get used to the grid pattern of one projector fairly quickly, but having two projectors will give your show much more variety, since the moving lasers from two grids will interact in unpredictable ways.
