I bought this to install new cabinets and it worked on about half the cabinets I wanted to put together. The design of the cabinets did not allow connecting a corner cabinet with a standard one. It's not a flaw in the bangs design, but there just wasn't the right lip on the face frame to allow for those clamps to be used. However, it has worked great on standard cases and the clips are definitely well done. Still worth buying. It was really handy.
