I've been putting off buying an air pump for ages now, I've got a plunger pump, though exhaust myself every time I have a guest staying, and then mean to order one. This is amazing! The box arrived this afternoon, it's very small, so tried it out straight away. A single air bed inflates in less than fifteen seconds and, even better still, deflates perfectly in twenty, far better than I've ever managed it. Guests are now a welcome addition to my home.
