Service was excellent and vents came in… Service was excellent and vents came in as promised. They are exactly what was needed. Haven't connected vents to them so I'll see what the sheet metal contractor says. The powdercoat has a high sheen which makes the vents reflect sunlight at certain angles. It would be better if a flat or satin finish were offered.

Aura Gravity Ventilator Our new 2 story home had a powered vent on the roof and was always running because the attic was so hot. The rooms upstairs were hot as well and A/C could not keep up. After replacing with a 24" Aura Gravity Ventilator and with the outside temperatures still hot, we could drastically feel the temperature drop in the upstairs area of our home. Not only is it cooler it is now quieter and we are saving energy. This is the second house that we have installed an Aura Gravity Ventilator, and both are now considered a huge success for us.

Great product great service The particular roof vent I ordered was great in both quality and craftsmanship and I consider the price very reasonable. The best part was that I called because I needed a simple addition to the vent and guy who helped me over the phone quickly understood what I needed and was very friendly.

Custom vent for greenhouse The custom vent was exactly what we needed for the flue on the furnace vent in the greenhouse. A size that was not readily available at the stores here. Prompt manufacture and delivery was another issue. The date promised with the purchase and the delivery were anything but smooth. It finally arrived days late and the only thing that saved the job was that the installers for the repairs to the greenhouse were also delayed in finishing the job. Things worked out but not without some good antiacids along the way!!!!!

after 13-15 years they still perform like it was day one i bought of pair of Active Vent retrofits -- 13-15 Years ago (!) to replace those useless turbine spinners -- i noticed brown spots on my ceiling - surprised to discover they were letting in rain and they were in good shape and spun fairly fast. i just took out the spinners - fit these retrofits in - they fit just right - fastened the standing vent pipe with some galvanized screws - easy peasy. Fast forward to 2019 - they still look great although the label has faded from being exposed to the sun - They do not let the rain in - and i live in the NYC area which saw back to back hurricanes - Irene in 2011 and the devastating Hurricane Sandy 2012. These retrofit vents will prob out last me.
