I was looking absolutely machine UV lamp, and have watched the prices of machines Institute I decided to come see who could find on Amazon. Reading the reviews I was very skeptical, I did not really trust this product. But I anyway decided to buy it because the price seen what good not try ... The product is ordered must be delivered 3 days after my order made and the machine first pleasant surprise came 48 hours after placing my order! 2nd pleasant surprise it was very well packaged and in very good condition. It is now two months that I have, and malgrès bad reviews, it works wonders. I recommend! If in doubt please contact me on my mail box: " [email protected] " Sincerely.
