Haven't used it yet as this was bought as a Xmas present for a family member.
Late delivery from Bikester
Unfortunately I bought it from the picture which looked like a metallic aluminium finish in the photograph - misleading I feel,as this pump is in fact white painted metal ( this is stated in the description - my mistake )
However it looks cheap at a not cheap price !!!!!.
Wouldn't buy the white or black painted models for the reason above.
Think you can get the white and black painted versions cheaper from other suppliers - so look round.
