Easy to use.
Fast delivery. If it works as shown should prolong my diesel truck motor.

It works
I hardly drive my RAM, causing my DEF system to crystalize and keep clogging up. I use this every other jug of DEF fluid for over a year now. Haven't had to clean off the injector once. I kept a 2nd injector in my console to swap out quicker.
