Worth the price
Nice cat aftermarket replacement, has the cat numbers on it so you can refill it easily at cat

Good value
Looks to be a good complete oring kit. Orfs, orb, flange orings. Only thing that would make the kit be better is the compartments had labels on style & size.

A real good kit
A cost effective kit to keep on my service truck. Has gotten me out of a bind several times.

The quality is rubbish
The quality is terrible, the hardness is not enough and there are serious burrs.
