Electrically, a perfect replacement for my Trane XVi air conditioner. As others have mentioned, it's a little bit smaller in diameter than the original GE capacitor, but that just meant putting in some two-sided tape to make the clamp hold it. Durability gets four stars until I get at least two cooling seasons out of it to know if it'll hold up as well as the 17-year-old dual-farad starter capacitor it replaced. However, after a month of summertime use, it works without a problem.
