Pros: - Compact, easy to store - Works well, as advertised - Auto Shut Off when desired pressure reached

Cons: - I found it to be a little confusing on how to set the desired tire pressure

Overall Review: Had a flat on a spare sedan and was going to have to pull the tire off the vehicle and take it somewhere to fill up. Decided to give this item a try in the hopes of not needing to expend that effort and save the time. After charging it fully I hooked it up to the flat tire and started it up. It performed as advertised, filled up the tire to the specified pressure and shut itself off when done. I've only used it once, so I don't know how long the battery will last, but it performed well for it's initial use.
