Author: Ryne P - USA - Jan 2010 The diffraction grating i purchased from dragonlasers is top noch. It provides endless enjoyment and i have made use of it many times. It is also a great way to spice up a party. Setting up a laser display is always a lot of fun, and with the diffraction gratings from dragonlasers doing so is no hassle at all.
Author: Ville K - Finland - May 2010 I got myself a Viper series 75mW pointer and the reflection beam fan diffraction grating, and have been a happy laserist ever since. The shipment was as fast as all the previous testimonials suggested. With full batteries it's even able to light matches within a few seconds if I'm able to hold it perfectly still, and it sure stings bare skin. I almost regret not ordering the laser glasses, because the laser dot is easily bright enough to create a small "sunburn" in the eyes after a few seconds even if not staring directly at the dot. My friends definitely realize its potential dangers and handle it with respect. The laser is especially astounding at night when the beam itself is clearly visible. I've been amusing myself and my friends with it for countless times. The switch button is however a bit prone to get stuck on. It's relatively easy to dig it back up but it's probably wise to be careful from the start with the button and not press it too hard. Otherwise the unit is top notch quality-wise and well worth its money. Using it with the diffraction grating in a foggy environment looks thrilling!
