Despite what people say.
I think these Sardo Racks are great. If you rack alot or have a back problem, these are a real life saver!
Sure if the balls are not clean or the cloth is old it will still be difficult to make all the balls stick together.
But at least with the sardo i find that the balls will stay in place. With a normal rack in similar conditions most of the times the balls in the middle will come apart more irregularly and the break looks really bad.
