Craftsman 12V Portable Inflator w/ Digital Tire Pressure Gauge —
It took 30 minutes to inflate ONE SUV tire, and five minutes of that time was spent trying to get the air chuck locking lever to close around the valve stem. What a pain, literally. I had to keep manipulating the depth of the air chuck on the valve stem in order to finally get the locking lever closed (with GREAT difficulty).
I also tried it on a bicycle tire valve stem, and the valve stems on the tires of a portable generator; all with the same poor results trying to get it attached.
Sure, this thing is loaded with features, automatic shut-off with a set-pounds feature, detachable digital air gauge accurate to .5 pounds, etc. But, if the product can't handle a basic requirement, like easily mounting on a valve stem; what good is it???
