I was really looking forward to receiving this turner, as I needed more turners for a large vendor event I was preparing for. It was easy to assemble and the price was reasonable, but it was very difficult to use. There is not enough space between the two tumblers to coat. I use water based Crystalac for coating, which requires multiple coats and it was very difficult to use this turner for the purposes intended. I would not recommend this tumbler unless you use epoxy (a one coat process) AND very small tumblers. Maybe it will work better for my pens. Otherwise, I will likely not use it for regular sized tumblers.
