I recently bled 4 tires with it. Here's my take: Pros: 1 Small/compact 2 Backlit display 3 USB rechargeable Cons: 1. Not very intuitive - if you don't use it often you may need to go back and read the instructions to remind yourself how set the maximum pressure2 . You can use a longer hose. On car tires, if your valve isn't down when you inflate, you'll have to leave it hanging (which isn't good in the long run) or put it on some sort of pedestal while you inflate.3. The display is difficult to see in bright light. Can be made brighter/bigger.4. I find all of these tire pressure machines a bit overpriced. Overall - he gets the job done and that's what counts.
