DEF Quality Good, Pump Fails Quickly
The DEF itself performs well, but the included pump is a weak point. The pump, which costs around $300, stopped working after only a few months of use. This makes the overall value questionable despite the DEF being fine.
Pros
- + DEF quality is good
Cons
- − Pump is unreliable
- − Pump died after a few months
- − Pump is expensive
