At the moment I can only make a valuation for receiving the product, as I am still testing it. Fast shipping in about seven days. Good packing and well protected. Bring the laser and its plug (only works plugged in), A s protective glasses and instructions in English. Very simple to use and fast. Once the result is valued I will comment again, but a priori seems to me a recommended purchase in your value for money! (A small detail as a gift accompanied my request).
