Awesome fan

I'm currently having HVAC issues which are causing my carpets to be damper than I'd like, so I bought this little blower to feel like I was doing something proactive while the professionals figure out what's going on.It works great! The exterior is a sturdy matte plastic and it feels very solid and well put together. It doesn't vibrate much even at the highest fan level. It's probably smaller than you're imagining, but it does output enough air for spot drying and does so relatively quietly.If you have a BIG drying job, like a hallway or room, I'd probably splash on something a big bigger or more powerful. But this does what I needed it to do, which is to give me a false sense of security and make it feel like I'm fixing a situation I'm otherwise powerless to change. And that's priceless.

Small, but excellent so far

Extremely powerful force of air circulation. Strong, sturdy casing. Sound is low except on number 3, but it's every bit worth to hear because of the air coming out. Love this. Already thinking about buying another one
