Great for locking diffs on demand
It engages instantly when needed on the trail and disengages cleanly on the highway — exactly what I wanted.

Quiet compared to others I've used
Surprised by how much quieter it is compared to my old compressor. Works great for topping off tires at camp.

Works fine, a bit slow
The Viair 400P Portable Compressor gets the job done but airing up bigger tires takes a little longer than I expected from the spec sheet.

Fast, reliable inflation
It airs up all four tires quickly after a trail run and hasn't overheated even on longer sessions.
