Product review (1 stars): this is one of those "beware and read the fine print" products
do not buy this product.  It comes without the tubing to reach up the chimney.  That has to be ordered separately.  i live on the first floor and ordered a recirculating kit to recirculate out into the air.  The kit cost $99.  the kit included the tubing that should have been part of the product and not an add on purchase.  They only thing usable was this plastic cap that seals off the air from under the hood.  For return, they required information you would probably do not have.  They want the order number that only came through email confirming shipment.  I don't consider this a problem.  I consider it swindling.  this is one of those "beware and read the fine print" products.
