Query: these lenses are great if you never get them dirty or need to ...

these lenses are great if you never get them dirty or need to clean them, because as soon as you do - the coating on the lens rubs/scratches off. its like looking through permanently dirty glasses that you can never get clean and it will drive you nuts. and don't bother with customer service. they don't exist. their website says they respond to being contacted within 48 hours, but Ive been waiting for 2 weeks for an answer to my multiple emails and inquiries - and haven't heard a word. the order comes with a free 'gift' microfiber carrying and a business card begging for reviews of their product... well, Lens Swap, here's your review. don't bother buying these flaky-jake turd lenses unless you love buyers remorse and being ignored by customer service. youre welcome. oh, I almost forgot to thank you for the free gift microfiber carrying bag - my cat loves attacking it and rubbing his face all over it. its actually held up better than your lenses!
