Excellent product. Well made. It saved me the trouble of having to make it myself, and it came with a rim mounting bracket (I didn't expect that) that the extender tip snaps into.
I drive a pick-up (P/U) truck and anyone familiar with them knows the spare tire is up under the P/U bed with the stem facing up! So, when you need to access the valve stem you gotta let the tire down. I have a very slow leak in the spare tire which over a period of time causes the low tire warning light [on the dash] to come on. Now I just reach up under with the air chuck, and, or, air gauge and service the tire like a gentleman!!!
