Review (1/5): BEWARE this is a total SCAM!!!!
I would have given a NEGATIVE five if there was such a thing. One star is too much for a product that goes straight to the trash bin. The silicon piece would not stick at all. It peeled off the double sided tape it was sitting on right after I put it on the nose piece and I ended up having double sided tape sticking to the nose piece and earned the trouble to clean it off.
