Had a leaky tire that needed topping up every 2-3 weeks so this thing came in handy. It works fast and has a handy portable size. The length of the cable was just right for my small sedan. For the amount you charge air pumps at gas stations, I've probably already got my money back based on how much I've used them! Unfortunately, the built-in sensor is completely inaccurate - I'll have to wait a little longer, I'll take it. Remove the tire and check the pressure with a separate tire gauge. This doesn't seem like a big deal until you need to inflate two or three tires. This can take a long time. Unfortunately, the fact that the gauge is inaccurate completely negates the usefulness of the auto shut-off feature. So if you're looking for an inexpensive pump that just gets the job done, this is the one for you. But don't expect much more.
