Got this for my husband to keep the grandkids bike tires inflated and all the footballs and basketballs around here. Ironically the day after this came, my husband had a flat tire on the jeep. He decided to try this out. He had charged it the day before so it was ready to go. He was able to enter the PSI and attach the nozzle. The compressor did the rest of the work and it cut off when the correct amount of air was reached. If it worked on this tire, we have no worries about using it on everything else. Wonderful product and a great price.
