This thing is great, works well, throws light farther than specified.  // Here's the problem I could not anticipate, because the description fails to explain the limitation of the remote control: the remote is infrared and the receiver on the light projector is on the FRONT of the unit, the end the laser projects from.  I bought this with the intention of placing it some distance from the house, aimed up a tree, but then it would be facing away from my house and to turn it on or adjust with the remote means going outside and standing in front of the projector.  If it had a infrared receiver on the back, then it could be set up in many more places.  As it was I had to abandon my plan and have it shine on the house.  Which is nice, but not what I bought it for.
