I bought this to have better airflow in my Mars Hydro 3x3 grow tent. It has worked perfectly for at least a year now. I change the pre filter every month, and I've had no issues at all with it. Great construction, easy to install in my tent. This will be a quality purchase.

I was really dumb and thought I had ordered the kit that came with the digital controller, so I was a bit sad and disappointed with myself. Still though, the product is good. I have no complaints with the quality of performance at all. Juts be careful you click the right thing and double check it at checkout.. I thought I had selected the right one but I must have stuffed something up along the way & didn't notice until it arrived

excellent fan very quiet and stealthy much better than some of the jet engines out there. filter still good after three grows.

Alles bestens. Alles im Lieferumfang dabei. Qualität passt und funktioniert wunderbar.
