I was very disappointed with the Sardo rack. (Should have listened to the forum on that one.)
Screw-on tips.
Aluminum cues (but I applaud the continuing search for an engineered substance that won't warp).
Laser cues: a modern update to a good concept, but I haven't seen one where the laser beam is really in line with the cue axis, so fail.
Disco-blinking, out-of-balance pool balls.
However, I think pool gloves are great.
