Highlights
Quality
Excellent quality insulation to the grow will buy more of their products.
Love the quality and ease of use.

Price
For the price point this inline fan is perfect!
Great in line fan for the price.
I got these for ten dollars more than only the hub.
Overall probably the best bang for buck if you want a quiet fan.
Packaging/appearance
The packing it came in was amazing also.
Competitiveness
If you need this to run any more complicated cycles than 10 on 50 off, you'll want the more expensive control unit.
You can pair other vivosun products with it.
