I purchased a bunch of these for a new oak dining table I made. Overall, they worked... OK... but I had to bend some of the clasps so they engaged a bit better. Sometimes they would slip past each other if I didn't bend them. The alignment/mounting, as other reviews stated, was sometimes hard to get just right. I had to adjust some of the holes on a few of these to get them to close properly. For the price, I hoped they would have worked a bit better.
