I have been using it for a few years now to inflate my tires every 3 months. I have successfully inflated 4 completely deflated tires from an abandoned car without any issues, so it performs excellently in its main function. However, it has 2 minor issues:

The first one is that its plug is screw-on and quite inconvenient to use. It could easily be designed to snap on like other pumps. Perhaps it could be modified with a patent.

The second issue is that, at least in my case, the + and - buttons do not do anything, so the automatic stop function does not work. It seems like I received a defective unit.

The job of the wrench is done poorly, but the truth is that I expected it to be much stronger. Also, its indications are all over the place. I regret not buying a black and decker or michelen with (approximately) the same amount of money.
