Simple Deluxe Adjustable Flow Outlets

**Update** I have tried everything to help the unit run cooler and quieter. It just isn't working. It runs so hot and that makes the air coming out hot. I can't imagine an instance where this would be a good air pump. Maybe in a room kept at like 50? I have no clue. I can't use this at all with my tank. For that, I'm glad it was only 30 bucks. At least I didn't waste double that or triple that. I was pretty pumped for this to arrive. I read all the reviews and they all seemed pretty good. It arrived yesterday. I plugged it in and got it all setup. The noise level was INSANE. After 1 night of running the unit was insanely hot and the hose with the control valves came off. I reconnected the hose and 5 min later it was sliding off again. This wouldn't be a problem if the unit didn't run so hot. I could use some plumbers tape to attach the hose to the output. I worry by doing so it may overheat more. One reviewer suggested attaching a hose to the input to dampen the noise. I tried it this morning and it worked. Except the unit was already running hot and I'm afraid it may make it run even hotter. I do love that it came with a 6 output control valve. That's really handy to have. I'm going to attempt some things to see if I can get the unit to cool down before considering it a total wash. If the unit didn't run so hot and wasn't so loud I'd total give this 5 stars. I took away a star for each of those plus another because until I can figure out how to keep the unit cool I can't fix the noise level or the hose popping off the output. I will edit this if I'm able to find a way to cool the unit down and resolve the hose issue.
