Easy to install, solid and does exactly what I needed.
I needed something that would allow my HVAC UV duct light to turn on and off when the furnace/AC fan kicked on. This unit fit the bill perfectly. I was hesitant for a very long time but the UV Light was on constantly whereas the furnace/AC was only running about 20% of the time so I was just shortening the lifespan of the UV Light. It installed within minutes, looks good and works like a champ. Now when the unit detects air pressure in the vent it activates the outlet which the light is plugged in and now the light goes on and off as needed, saving both electricity and life of the UV Light. HIGHLY RECOMMENDED !!!!!

It works very on my fan. But Do not know the durability and reliability. Will see how well it goes within one year. And two year, and much more.

Works great
Works very well to turn on and off booster fans and other accessories. I am currently using it to switch on a whole house HVAC oil diffuser system and it’s doing a great job.

Difficult to get working
I bought this to control a duct booster fan. I followed the instructions and installed it in the main plenum close to the furnace. It didn't work so I repositioned it a little further from the furnace and again it wouldn't work. In desperation, I moved it to the end of the plenum with similar results. I was removing it while the furnace was running and had it part way out when it started to work, pushed it back in and it stopped. So its currently hanging out of the hole in the duct and working perfectly.

Works...read review.
I got this to power a couple of boster fans we had added to our HVAC system. I installed according to instructions, even used a level. It worked great for a couple of weeks then started to have issues like it was surging or rapidly switching on and off. I pulled the switch to make sure it was clean and not blocked, same issue. Pulled it again and tipped it about 10 degrees back and now its working as it should. I will update in a month or so.
