Bought a year ago. Behavior that small, compact. Dropped and forgot. Considering that in 10 years of driving I used the pump a couple of times, and once due to a puncture, the compactness played a role. But now a stroller appeared in the house, which periodically needs to be pumped up. And after a couple of such swaps - the pump died the death of a nifiga not brave. Google "mai compressor died voltage stabilizer" - there will be so many wonderful discoveries. In general, avoid the light version.
