I ordered 1 set first and didn't read the reviews. All I got on that first order was a top clamp but no real connectors. Since I really needed these connectors for a project, the next day I ordered 2 more sets (I have to love Prime!), knowing full well that I would be rolling the dice and praying to get a combination of 3 set pieces that would work. I got lucky and one of the two sets was much larger and had both real bushings and caps, but to date no one has had a third piece of the spanner. Now it's not Revain's fault, the seller double boxed them so it's really a reflection that the seller either doesn't understand or just throws the parts away. from one of the major electronics manufacturers. It's rolling the dice, but it's gotten enough bad reviews now that someone is probably going to do something about it. And frankly, for the price, it's still a good deal.
