Hi Jon
Not for me I am afraid I am a stepladder man. Looks very unstable and when you have got the item out of the bin how do you lower yourself?, as it looks like both hands are needed to operate each shoe lift. Or is a case of finding the object and then going to find a stepladder to remove from bin? Other than that what a great idea . I am sure with a few more years research it will find a place in industry.

I would like to add I hate heights and will not be rushing down the workshop to make a pair 😆
