Off lease laser is one of those "businesses" with a nice web site and fairly efficient customer service but when things go wrong, and they will, expect your calls and emails to go unanswered. When they encourage you to pay with a wire transfer for a discount, please do not fall for this tactic, you will , like me, spend the better part of a year slowly and painfully negociating to get a refund. What legitimate company would ship you an old broken laser when you were told it was , of coure, if perfet condition? A company that is on it's last legs, that's who. Dont be fooled, call to the various other vendors of medical lasers and be careful, there are many reputable vendors but off lease laser is not one of them. Again, charge your purchase if you buy anything, you wil never see your money back otherwise and your laser comes in dirty and inoperable, dont say I did not warn you. I am a physician, not a competitor, I am frustated that my refund never came and did negociate in good faith for the better part of 6 months so whatever off lease laser may say ,why ask for problems, go elsewhere.
