I have seen these devices on the market, for a while, at around the £50 mark, but most have poor reviews for reliability and the ability to pump up only small diameter tyres.
I spotted
THIS one, available from Aldi at £29.99 delivered.
As it has a 3 year warranty, I thought that it was worth a punt.
It works well and I am very pleased with it.
A good option over using a garage pump, a foot pump, or trailing a wire from the power socket.
Ideal, for lazy people, to pump up their tyres and other inflatable devices.
