Query: Shoulder Dolly is a back saver

I've used this product once and found it to do everything it's supposed to do. I loaned it to a friend who is moving to another house. He and his 'moving buddy' want to purchase one. I helped move a washer, dryer, and an upright freezer. No problem....and no backache.Amazon also has the best price of anywhere I looked, even the 'discount' hardware stores.
