Review on High-Performance TR90 Bifocal Sunglasses - Ideal For Motorcycle Enthusiasts! by Luis Blaschko

I bought these for use riding motorcycles (with a helmet). Air leakage around the rims was more than usual for even normal, everyday use, sunglasses.So I used them for everyday use, and within a week the rubber nose pieces that fit on over two slim posts on either side of the nose, fell off and was lost. Before I'd noticed the rubber pads were missing, the two slim posts that the rubber pads fit over, cut holes in my nose.Later, I found the rubber piece and put it back on, it quickly was lost again. This time I contacted customer support and asked for replacements. There was no response.Later I miraculously found the nose piece again, and super glued it back on, but a bit of the glue got smeared on the lense, and became bothersome. Never did hear from customer support. I chucked these in the trash, won't buy any products from these guys again.
