The AO Smith/Century motor on my Hayward pool pump was nearing the end of its life due to worn bearings and was in such bad shape overall I couldn't repair it. After searching the web, I found this model at less than half the price of the OEM replacement, so I took a chance. Glad I did. Came extremely well packed, and looks very high quality, but the proof ins in the install. Replacement was quite easy (get a seal kit for your pump) and the pump fired up right away, running smooth and quiet. The only ding I would say is that you can't expect the standard amperage draw they list as 240V/6.8A. That may be with no load, but when running the pump I measured about 8.1A, close to the stated max load draw. Still a bit better than the OEM, so I'm happy so far.
