Inyoupools offers real stuff for pools. In my case, I purchased a starting capacitor for my Polaris pool pump motor. The capacitor arrived on time (5 days). I installed it - and the motor works. A $40 part saved me $549 for a new pump.
Last week, and after removing the entire pool pump, I watched a video on YouTube that suggested the starting capacitor was bad. It turned out to be the case. I had to re-install the entire pump when I could have simply tried the new capacitor first. Live and learn - the motto of the DIY world.
