Product review (4 stars): Very attractive
Update to Review. I originally gave this a rating of 3 stars; have updated to 4.  My original review still stands but I've learned a few things. First, the customer service of this company is OUTSTANDING! Called with an issue and the call was answered on the first ring. I wasn't sure if I was creating a problem with the clock or if there was an actual problem. The customer service rep was so patient and helpful.  Turns out, I was the cause of the issue, not the equipment. Throughout the call, the rep kept saying that they'd be pleased to send a new part. Not once did I feel put off; if anything, this company wants you to be very happy with your purchase. In my first review, I mention the quality. Given the price point and design, the product does exceed expectations.

Original Review: This is a very attractive unit, but the build quality is very Chinese. Instructions for installation and operation are pretty much non existent. However, a call to the very responsive customer is very helpful.  There seems to be a confusion if this unit can be used as ventless. The answer is yes. Just buy the 2 filters designed for the unit. It does a good job of removing smoke and odors; however, this unit is not quiet, especially on high.  Figuring out how to use the control panel is a bit challenging. There are preset levels that get you going quickly. Have fun figuring out setting the clock. If you're looking for a high quality built fan, you may want to look further. If you're buying with appearance as the primary factor, this is a good choice. It does the functional job but the materials and build quality are lacking. Packaging is good but mine came with a couple of dents in the back. Decided it wasn't worth the effort to go for a replacement.
