I like the display idea but wish the display screen was even bigger if the desired set pressure wasn't so far away. Set the pump to 22psi, it will stop at 22psi, use a tire pressure gauge and the pressure will be 4-5psi more. It inflates a tire quickly, is lightweight, versatile and easily fits in the glove box of my Polaris rzr. Also the idea of a rechargeable battery built into the pump is a great idea. The reason for the 3 stars is solely because it is inaccurate for psi tuning.
