Limited review due to the fact that I haven't installed it yet. It was in a repacked carton. The interior of the box was filled with broken Styrofoam that seemed to protect the pump. I hope this is a new pump, it looks like new.. Yet the pump inlet on top was open and I had to vacuum the foam debris (hopefully I removed it all). I won't know how well it works until I install it because I bought it as a spare.
