Wouldn't install, and NOT RETURNABLE.
This product seemed like a good idea, but even after following video instructions, this product just would not stay in place on my glasses.  I tried installing them dry (you're really supposed to wet the glasses and this product with water), and they kind of stayed in place, but I just couldn't get the bubbles out so the vision was distorted.<br />Also, be wary, because this item is NOT RETURNABLE.  For some reason, the product page does not state that this item is not returnable, but when I tried starting the returns process, it told me it wasn't eligible.  I called Amazon, they saw this, and very graciously refunded my purchase.  The seller needs to make this clear on the product page.
