My gauge is somewhat the same, where it will "stick" for 10lbs or so, but once it gets moving, it keeps moving for me. It's not a replacement for your floor pump, it's not a dedicated gauge, and it's not a real expensive piece. It gets the job done and makes inflating on the go as easy as it gets. I don't think one should expect precision from it, especially for the price and compared to what else is out there.
