After only 2 months, the piece will no longer thread onto the tire stem at all, rendering the pump useless despite all other parts of the pump working fine

Only fault is that the air chuck became loose and threaded quickly.

The thread is kind of hard to twist on/off.

OTHERS HERE have commented on how easily you can ruin the threads on the air pump valve.

After a year of use to maintaine a tire that has a slow leak, the threads on the chuck (where the hose on the pump connects to the valve on the tire) have degraded to the point that I cannot connect the pump to anything

The Main problem is the thread inside of hose went bad on both of those

I love the thread on inflator hose that stays firmly attached the stem valve without you pressing your cold numb fingers down on it the whole time

A design suggestion would be to change to a Rapid-T Valve (like found on good bike floor pump) to clip on rather than screw on to attach to the tire

works as it should.

The product works as it says

I suggest reading directions on box as well as on the user guide.

In fact the pump showed my bicycle tire at 67psi at the end of the pump, after I removed the nozzle as fast as I could the pressure was below 50.The fact that it died so quickly and others have commented on that as well, says they need to QC the product.

I purchased this compressor for my recumbent trike tires, as well as for my car
