Okay, I admit that I do not use it all the time of its UV lamp ... but it is really effective.
If you have the habit of using UV lamps for Counterfeit detection if you make the sale, it is a useful combination nomadic !! Otherwise, the cleaning utility is still more technical, I must never have tried!
Big advantage, I find: with its small size, the attachment strap is really convenient! a good, sturdy object to recommend for all terrain! :)
