Sometimes I see reviews that ask so much of a product, even when the product is cheap (as in costs very little compared to others). Is this a set of expensive, designer glasses? Nope. So taking that into account...

The product does what is says it does. It flips up.... and down. It's canary yellow... etc, etc. So I got what I bought, at the price that I was told.

Great! Five stars.

End of review  :)
