Review on TEKTON Universal Socket Set - 10 Piece (Model: SHD91119) by Mark Gardner

Essentially just a flat head on a U-joint, but a piece. My only caveat is that it's only 6 points; I deal with a lot of 12 point bolt heads at work and a 12 point set is much better for me. But whenever I needed them for 6-point attachments, they performed at least as well as I expected, if not better. These things help keep airliners in the air, so you know.
