They are complete garbage...
If you have ever looked at the internal workings on those racks, you will see they don't actually "push" down on the balls and make them tight as they purport to do. The racks don't even touch the balls as you push down on the handles. Haha... This theory would not work anyways because how many times do you push on the balls with your fingers only to have the balls move as soon as you pull the wood rack.
The whole premise behind the rack was to "train" the table first which meant set up a rack of balls on the table, then proceed to tap on each one until there was a clear indent in the cloth. When you went to rack each game, the balls would merely fall into the holes.
We used those on the IPT and it was such a gaff... Half the players were not even using the racks.. you could just form the balls into a triangle and push them over the spot and they would sit in the indents. Nice...
Yep same experience here. I was playing at the Derby several years back and the match was on the farthest corner table in the room. There wasn't anyone within 150 feet of our match. We couldn't get the damn thing to rack tight. So my opponent finds another rack and asked me if I wanted to use it. Hell yes!
I start racking using the "other" rack. Within 30 seconds, here comes Lou Sardo from nowhere, admonishing us for not using the Sardo rack. We tell him that it's not working. He laughs like it wasn't possible for the rack not to work. He then tries to rack with the Sardo and has the same results. He spends the next 10 minutes re-training the table. And it worked like a charm :grin:
I do have to give the Sardo's some credit. They put their money into sponsoring tournaments on a product they truly believed in.
