i wouldnt say just because they are wax polishers that they are crap they do exactly what they are designed to do and that is polish unless you have your very own ball spinner (which i doubt everyone does) then like i said they do as required and to me if the machine is running well then they do a great job the ones at Bowland Ingle Farm and Salisury do a good job at polishing so if your looking to get your bowling balls polished id consider going there
