Excellent device of professional quality (hence the price, but it's not a toy ...) and very intelligently designed. First, it is beautifully dimensioned to its grip (not too big, in particular); And two, its intuitive menu on the screen, is a perfect clarity: in five minutes, even without looking too closely the user manual, you control just about everything icon icon, and become already virtuoso calculation surfaces or even adding volumes (with storage library). It is also bluethooth but now not tried is beyond me. Only small thing if we had really find fault (because I am fat): it takes three batteries (small R3), which is not practical consumption of it. Better would have won outright predict four, for an even greater autonomy. In fact, if you are an individual, absolutely keep out of reach of children, so this gadget is apparent core and fun to use. Because we are dealing with a laser beam, terribly dangerous to receive in the eye, while if for fun funny to aim between kids from a small red dot in films like Robocop or modern hitmen and infrared guns or style Star Wars (and I found that the manufacturer did not insist enough on this danger, although the instruction manual includes an ad hoc warning sticker to attach to the device). PS The maximum range of the radius of 50 meters; so this Mr. Louis XIV had given to measure this poor little venues and you drag he called his Hall of Mirrors.
