Slow shipping. Doesn’t come overnight
Received in a couple days, not next day. Fits identically to the initial it replaced
P**)
No bleed diamond resistor all quality capacitor should have that
No bleed down resistor. I think a quality capacitor should have that I should have noticed in the pictures. I would have purchased a different one had I noticed that.

Defective
Exactly like the one I wanted to replace including inability to hold a charge. It was defective right out of the box! Returned for replacement. I’ll give them one more chance.
