Product review (5 stars): Perfect fit!
We had our AC inspected before we sold our house and the tech said the capacitor we had was out of spec. It was spend $$ on this or $$$ for him to replace it. I went the cheaper route.

Extremely easy to install!
Disconnect power to AC unit (most should have a power disconnect next to the unit)
Open the cover
Find the capacitor and verify the values match (if possible)
Take note of the existing wire connections
Disconnect the old and connect the new
Mount the new where the old was using the existing bracket or the included zip tie
Make sure no wires are crossing/shorted and close the case
Connect power again (at the disconnect or breaker panel)
Enjoy your working AC again!
