Bought to use with a new air bed, the pump adaptor fitted perfectly to the bed and inflated it quickly and with minimum effort. The only drawback was a high pitched squeak at every compression but that was asweet small caveat for such a cost effective and immensely practical pump.
Switching the adaptor to the pump's 'deflate' socket allowed the pump to extract the air from the air bag extremely efficiently and we did not have to squeeze any more air out before rolling up the bed for packing. The tube for the pump coils around it when not in use and the pump can be compressed and held imposition with a simple tie to keep its compact as possible for storage.
An outstanding success and very good value for money.
