Item is cheap plastic junk, do not buy. Frame snapped fitting the first lense. Buyer refused to refund - no avenue to appeal.
I can't leave feedback, about this product, but the service is not good. I ordered this product on June 3. and it was information about "delivery" to the Czech in September. It took too long time to send this product. I have moved abroad, so I couldn't pick up the product at the post office, so I am still dealing with the problem with delivery. When I did order this good, there was information about delivery in 40 days, but it took 3 months. So I don't have this product.
