Review on Flexible Valve Extenders Stainless Extension Tires & Wheels by Brian Krump

I installed these on my motorhome last weekend and was very disappointed. The "clip" that holds the extension in place is so flimsy that part of the valve slips right through the retainer when you press the gauge or air nozzle to inflate the tire. 2 nuts on each stem to attach it would fix it. They appear to be of good quality and no leaks, they just lack a few details to make them 5 stars.
