Review on 🔧 Boulder Tools Heavy Duty Rapid Tire Deflator Air Down Offroad Kit – Precision Release Button, Glow-in-Dark Feature – Bonus: Valve Caps, Valve Cores, Valve Repair Tool – Fast Deflation for 4x4 Off Road Tires by Tyler Blake

I originally received it and it was easy to set up. Read the instructions and it works very well. I was pleased with how quickly and efficiently I was able to deflate off-road. However, the third time you use the handle to turn the unthreaded valve stem, it seems like poor design if the threads go in the same direction you have to turn it to unhook the valve stem and deflate. I secured it to the threads with a bit of Loctite and it has been working fine ever since, but it seems to be an oversight as they didn't put the threads in the opposite direction so it was tightened when you loosened the valve stem or already Loctite applied until he could not free himself. There doesn't seem to be any reason why it would ever need to be removed once built. Overall I'm happy with it, but I think it's a good product, just be prepared to put some Loctite on it in the future. (Although 3 uses isn't that far).
