I ride every day and use it to inflate my bike tires It's easy to use and works. My only problem is minor. Small text on the display. As the first reviews came from the UK, it was obvious that there was no PSI by default. Switching to PSI was easy as I used a magnifying glass to see the screen. I expect non-seniors to see the measurement parameters more easily. The numbers were a good size. After installing the PSI, connecting to the tire valve and inflating the tire is much easier and faster than using a hand pump. I also like the flashlight option. The device is too big to be attached to the frame, but fits easily in a carrier.
