GBthese appear to be high quality columns They were delivered 6 days after ordering.. One of the beds had pressure when i removed the cover the other didn't. They installed normally... The thing that impresses me is the smell.. normally when i change sieve beds they have an odor that takes my breath away until they break-in these don't have that odor.. I hope that's a good sign.. The machine is working at optimum efficiency now So far I'm extremely pleased
