I found the first time I hooked it up to my front tire I only had 40 PSI in the tire, drastically under inflated. Some of the reviews I found said people were having an issue connecting the pump to presta valves, but I have not had a problem. I simply rotate my tire to where the valve is at the bottom and press the nozzle onto the valve until I get a pressure reading and then I lock it down. I can inflate the tire to 100 PSI or more in a matter of seconds. I would easily recommend this pump to anyone looking for one.
