Query: Poor quality

This is a flimsy product. There are better ones available, so don't buy this one. I bought two of these. On the first one, the plastic hole that the mounting screw goes through broke as I tightened the screw with a cordless screwdriver. I then installed the second one, carefully tightening the screw by hand so I wouldn't break it. Even with the mounting screw snugly tightened, the adapter rocks from side to side. I bought a similar adapter from my local hardware store for the same price that doesn't rock (sorry, I don't remember the brand of that one.) Two stars only because it's inexpensive, but sometimes you get what you pay for.
