This booth is identical to the HSeng one but at least $50 - $75 cheaper. It is somewhat larger than most on the market - a considerable advantage. Experts have challenged the ability of these smaller booths to perform their designed function adequtely, but I found that the dual fans of this unit deliver some 175 CFM greater flow than the minimum required, given the booth volume. Some of this would be lost in the duct (which is of good size, design and quality), but it will still do the job adequately. If expert reviews worry you, accept my review as a recommendation for this booth, despite their warnings. It works - thank you Vevor!
