Excellent review and photos. I was hoping you'd post a photo with something like a hand next to the unit for size reference but your photo where you stuffed it into the back seat cubby did fine.
I agree about coiled air hoses in this type of application. They are stiff and quite often become a nuisance when they catch on things like a tire as you pull the air chuck around to where it's needed.
Those inflate times were great but would be even more meaningful if you also included the tire size.
Looks like an excellent, professional product that should last a lifetime.
