Review on 🔌 Milton S-693-12: Extended Reach Dual Head Air Chuck for 1/4" FNPT – A Convenient and Efficient Tool by Troy Simpson

Suitable for twin wheels in a camper van but as I couldn't get a perfectly straight shot of the valve stem through the wheel the open grooves gripping the valve stem made it very difficult to use. I removed the insert and filed the grooves a bit (quite tough stuff and needed a good sharp round file). Now it works fine.
