All user reviews of 4/5 for the JB Systems Radiant Laser

360mW bicolor, fast, robust, comprehensive ... At that price, what more?
Slamming a green, a beautiful blue (not wavelengths head sorry), even in broad daylight on a concrete wall he sees (indoors of course).
Various effects, dynamics, some rarely seen in these prices, a broad coverage, in short, a good product that works in small as in the great outdoors. Finally, when I say small ... careful to remain within the standards anyway, do not plug it in a room.

Small problem: there is a noisy but it's easy to forget when there is background music.
