I bought this pump in Aug 2018, sparingly used it to top up car tires before long rides. On one occasion I topped up 3 tires of my car and for the 4th tire, the pump died refusing to start. That is disappointing considering it ran for less than 5 mins. Since the pump has a year warranty, I contacted the company through Amazon - no response. Then I contacted them on the email address given on the box - no response. The pump seems to perform brilliantly when it was working, but unfortunately, it died within warranty and the worst part is that the company is not responding.
