Solid capacitor and still going strong.
I ordered this capacitor as a replacement for my Lennox AC unit, and it worked exactly as expected. It was as per specs, and when I tested it with my multimeter, the readings were well within the stated ±5% tolerance. The installation was straightforward, make sure to cut power first and double-check the wiring labels (C, Fan, and Herm are clearly marked). Once installed, my AC started right up without any issues, and it’s been running smoothly since past 2 months. It’s built to UL and CE standards, and the terminals and casing feel solid and durable. For the price, it’s a fraction of what a local HVAC company would charge just to replace a capacitor. I was quoted 350 with the final offer of $280. Overall, this is a quality, no-nonsense replacement part that does exactly what it’s supposed to. Highly recommended.

Out of spec out of the box.
Arrived new, but out of spec and unusable. Bought a 45/10 and it arrived labeled as such, but when tested it was exactly a 45/5. Totally wrong.

HERM, FAN, and C all easily readable on top. Can't speak to longevity, but out of the box it meets specs according to my cheap multimeter. See pics.
