GBHappy The price was good.It took a few days before it shipped, but still got it in a week. The tracking number was not linked so had to copy and paste each time to track the delivery. That was kind of a pain, but overall good experience.

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

GBI needed to cancel my order and… I needed to cancel my order and customer service was so friendly and helpful. In an age where people don't care about doing the right thing, and that can put you out of a lot of money, this company cares and made all the difference. Thank you!
