I got this air filler and pressure gauge because I need it to get into a tight spot and the end of this hose is quite low. This work is good for things that can hit a bottleneck. The only reason I rated it 4 starts is because the sensor works but won't start up to 10psi, it has markers for intermediate readings but moves in increments of 10. Seems like the resolution should be a little better. This is a good tool and at a good price. I would recommend this to others even if you need to use a separate gauge for low pressure applications or for a more accurate pressure adjustment.
