"Excellent design principles but readings a bit erratic especially when checked against another pressure gauge. Close - yes, variable - yes. As it says it is only approximate so cannot complain too much. As others have said neat & easy to store hose & cable &, pumps quickly. How long it will last - not sure but for what I need it will suffice. Pity they cannot get this type of pump more accurate as it is a handy bit of kit to have around."

Review 4 for Ring Automatic Digital Air Compressor with LED Light 12V
"I've used it only a couple of times. It does what it says on the tin. It pumps up quickly to a pre-determined pressure or you can stop it manually. It is better then some because tidying away the wire and tubing after use is less fiddly.. A bit pricey, even from Screwfix.
