Huge fan. I have been running them for over 18 years now. I have one that is 15 years old and still going strong, an AC 500. There isn't a better hob filter on the market and I would put a few of them against an FX5 in a second. Solid performance, longevity, consistency, easy to maintain, and if one stops you still have another one or two so you don't crash your system.
