Purchased this unit and it is everything the company claims. Features are realy top notch at a budget price price. But the instructions related to fastening the seat were unclear  resulted in the installlation takeing about 30 minutes longer than it should have. Also, the plug was pretty small and I needed an exatension cord to attach the unit. Those are the only complaints I have after a few says. The reliability of the seat  will remain to be seen, but I am comforted by a three year warrantee.
