So far the UC30 is working just fine. Took a little bit of time to install by one person, Two people would be better. I would suggest including a template of hole location that you could place under cabinet to help with marking the holes. The range hood looks great and at first thought I had a problem because it looked like there was an angle from front to back but after checking documents find it was just fine.
I was replacing an old Broan that was barely functioning. This was the perfect size, had good air flow, washable stainless steel filters and good lighting. I have venting to the outside and the dimensions worked great. I did the install by myself, not totally recommended but it worked out. High quality product.
