This gauge is easy to use and gives accurate readings. The soft case seems overkill, but it's nice to have this model and makes it a good choice for a gift. While the connector at the end of the hose rotates freely for ease of use, the other end of the hose threads onto the stem. . On first use I somehow accidentally managed to unscrew it! In the photos you can see three rings at the top of the stem. This is a threaded part so be careful not to twist it. Two tiny discs of plastic fell out, one black and one clear. I didn't even notice at first. In fact, the transparent one on the floor was practically invisible until I shone it with a flashlight. There was also some spring. Luckily I cleaned and put the discs back in and everything was fine. The dial is easy to read in the light. I assume it theoretically glows in the dark, but only if it's been "charged" with light for a while first, making this "feature" pretty much useless. On the other hand, who checks their tires in the dark?
