Vivosun

The little vivosun circulation fans are great. Could be one or two more speed settings, because they tend to be too weak or powerful depending on where they are positioned. But I'd probably have the same complaint with an oscillating fan and the amount of space saved is invaluable. Would order again.

The best in test

All Vivosun reviews from me are going to be 2 stars from here on out. Crowdfunding loans as one of the largest and most established cannabis cultivation companies globally is such a pathetic look IMO.
