I recently bought a couple flters and misc items, I made a mistake and ordered the incorrect replacements for two of the filters. The Service department dropped me a quick note with in 2 hours verifying this is what I wanted and they promptly updated the order with the correct item and then within 24 hours all the information related to shipping. I have ordered a lot over the internet, but never had a company with suce fast responses and action. I know I will be making repeat purchases.
