Bests & Worsts Reviews from Amazon

I've had this for about 6 months now (purchased October 23rd, 2018, reviewed April 7th, 2019). It is very accurate, repeatable, and easy to use compared to the stick gauges we're all used to. Vondior contacted me shortly after my order to ensure that I received the item and it was working correctly. With the first unit I received, I noticed that when taking the gauge off of the tire valve, the pressure would settle about 1-2 psi lower than when it was on the valve. I responded to Vondior's email simply asking which reading would be the most accurate. Vondior promptly responded that this was not correct and that they'd ship me out a new one no questions asked, free of charge, and without having to send the old one back in. I've never had a manufacturer initiate a replacement without at least a light demand, let alone of their own volition. The second unit arrived without the above issue in less than a week. This purchase involved the best customer service I've experienced on Amazon.
