“I have yet to use this one that I have recently purchased but have been pursued by Ring to do a review. I have an older version of the same model which is in my wife's car. It is easy to pre-set the desired pressure for the tyre. If the pressure is already too high, there is a bleed button (it fell off and got lost but there is a remaining pin to press) for letting air escape. Once at the desired pressure, you need to be quick in unscrewing the connection to minimise any further loss of pressure. It is not the fastest inflator nor the quietest, but is a solid reliable workhorse.”
“Excellent tool to keep in the car - I have one in both mine and my wife's car. Inflates the tyres quickly and easily in addition to the other features contained within the tool. Easy to use. Great price at the present time (7 July 2023) with 20% off and free delivery. Highly recommended.”
