I bought it in the first place largely to give the franchisees time with one - they each spent a week with it.
I've stated many times that while a weight difference might not actually be noticeable on a day-to-day basis, it's still less wear and tear on muscles and joints, but they all decided it wasn't worth the price premium.
I carried on with it for a while but my cleaning time is slowly winding down and I'm getting rid while it's still in good nick.
