Review on Instapark Valuepak General Purpose Protective by Michael Miner

Great before, especially for the price. I've been buying them almost monthly for over a year now and loved them until the last time I bought them 3 times. The hinge screws on each pair of my last three boxes weren't drilled through, so they just twist and fall off the front of my face if I look down a bit. They really had a big mistake in quality control. I used to like them, but now they're practically useless.
