It was a blessing very quiet extremely durable fit in my tent exactly where I needed to and the quality of the fan and the filter must superb.

Quiet works great... runs on a timer that has various settings which is nice.

We have a greenhouse and garden operation for veggies and herbs and we use tent greenhouses for seedlings starts. This device is easy to set up and keeps humidity at the right level and it keeps the air moving. It does so very quietly. The result is fast growth with hearty and healthy seedlings for greenhouse and outdoor gardens.

I'm not sure if it's actually the best, but it certainly has a couple of stars shining for it. Easy to install (15min), wireless app control, great airation and fully compatible with the other gadgets vivosun has to offer. Love it
