I have had one for ages but tend not to use it cos as soon as I try to apply pressure on a spanner, equal and opposite reaction sends me sliding off in another direction and the nut or bolt stays undone! And it don't matter how I position the creeper as the thing is on castors they just spin to make said travel possible.On account of advancing age ----- and waistline----- I have squandered me pocket money on a car creeper. Luxury model with 2 x magnetic tool trays, and a LED work light on a bendy stick thing. Should make getting under the family fleet of low slung front end cars a bit easier from now on. Especially the focus which almost hugs the ground with its nose. And I need to add a couple more inches to the height of the home- made ramps. The 1970's ramps which are still in good condition, and still useable for raising the rear end, are no good at the fronts of moderns. Looking forward to sliding around under the Landy too
However it does also transform into a seat with a lickle back so I use it mostly like that!
