I got a very similar product from Woot some months back. Same leg design, but different pad and fan design. I’m extremely happy with it all around, helps with cooling my gaming laptop, slightly tedious to set up but adjustable for using in bed or in various positions at a desk.
My only gripe is that the third-party Amazon seller that fulfilled the order shipped it in only a thin plastic envelope that tore open in transit, losing all the small hardware necessary for the mouse board and resulting in some minor damage to the rest of it. I got a refund and kept the surviving product, tho, which is a credit to Woot’s customer service 
Excellent and useful product, just be aware third party sellers that fulfill Woot orders are sometimes totally inept, and it just might arrive with missing hardware
