I'll second that. I have installed a couple of them but really never have been able to feel all cozy about the things. They just aren't as "bulletproof" as I believe a seal should be and there is no second chance.
Larger versions of mechanical shaft seals usually incorporate an inflatable bladder to seal the shaft when the seal is damaged or fails.
