All those capacitor are good. I have used AmRad, it fails after 2 years, called them and they sent me a replacement.
IIRC, they have 5 years warranty.
Another important thing is the maintenance.
It is like cars, the condenser coil needs regular wash, regular filter change and condensate drain maintenance.
They will help with capacitor, contactor and fan motor to last longer and besides makes the AC cools better.
Checking capacitance with cheap meter from Amazon can help diagnose weak/bad capacitor.
