Perfect Run Capicator for Pool pump
Worked great on my Super Hayward 1 HP pool pump. The original run capacitor is rated 50-400 uf. I read up a little and understood that original run capicator when burns out, makes a humming sound but impeller freely rotates when manually spun around. It may help others to know that you are good to go up a notch on microfarad but not down. I ordered the Upgraded Version 340-408 uf 110-125VAC BlueStar capicator. It was easy to install (I took one wire off at a time from old capacitor to make sure all three are similarly placed). BlueStar capacitor was perfectly sized. It seemed to have a better physical construct quality than the original. Btw I am not a super handy kind of guy but this was easy. Run capacitor is only two outside screws and one inside screw away on an Hayward super pump 1HP (gold). This cost me a little research and 13 bucks, replacement took me 10 minutes max —- saving me hundreds in service/ replacement costs! Few days in, it is going strong. Easy, fast reliable start. Would definitely recommend!!

Perfect fit and fixed my issue
Fixed the problem on my lift. Just be sure the number on your old one exactly matches the new one. And check measurements. Price was a fraction of the cost anywhere else! Other than that I am very pleased and back to lifting cars on the rack!

It was a perfect fit and exact replacement
The product was great but the packaging was not enough for pieces to break off in the envelope it was delivered in. We made it work, but it should be done with a box. Would have been 5 stars except for this.

Worked fine for my craftsman 60 gallon compressor! Was not the same diameter so just wrapped it with black tape to make it fit in the covers !

It’s working for a week no problem, I measured the capacity it was 321uf and the size was fit to original position . I give four stars because I used it for air condition starter and it doesn’t have the discharge resistor , I installed a resistor.
