I used my Pinball skates today for the first time and they work better than I could have ever imagined. I used them on a JD, which is no light pin and they made the moving task easy as pie. I would highly recommend this product to anyone. Especially if you live in a large building like I do with a great distance to the parking lot. Below is the seller.
