I bought this from Thomman at the start of the year. What first attracted me was the reasonable price and comprehensive list of features. When it arrived, however, the remote that is included was broken. This was in no way Thomman's fault, and I suspect it was due to poor handling from the postal company. Thomman very kindly sent a replacement remote free of charge.
I first used this at a birthday party, however, as the remote was missing, I could only use it on "auto" mode. This proved very effective, projecting a variety of patterns the full length of the room.
I learned that to be most effective way for me to use this was to have it set to auto for the first half of the evening, then as the music gets louder change to "sound" mode, which uses an internal microphone to match the laser beam to the beat.
Overall, this is a very effective bit of kit, looks great, and is still working brilliantly 6 months later.
