I bought this as my old pump had had it's day, giving off wrong readings for each tyre ... so when I saw this at £10 I thought "Why not?" .. so I did.
It came next day and I gave it a test run, checking all tyres to check the accuracy ... spot on.
Due to its size is does take a little longer to blow the air through, compared to the last beast I had, but it gets there quick enough.
The screw on fitting is great, I prefer this to the lever fitting of many pumps, and attaching it is a breeze.
once attached to the valve, and the power connector is plugged into the car, it's a matter of pressing the yellow button and simply waiting .... once the pump reaches the pressure (PSi) just press the yellow button again and unscrew the attachment. Job done.
The attachment tube? clicks into the body of the pump but the 3 metre power cable has to be wrapped up seperatly of crammed into the small gap in the back.
It does come with a couple of adapters for other tyres/infaltables, which is a bonus.
In all. Well worth the money.
