I think I'm in the minority... I recently got it and, while it works, it takes more manipulation to get the balls frozen and gets kinked and out of shape fairly easily. For a "perfect rack" system, I prefer the Slug Doctor. With reusable paper reinforcements, you can remove it if you don't want to use it, or you can keep it on the table. After putting it on the table, you also have a 100% repeatable rack- unlike the MR, which is subject to user placement.
Neither is perfect, but at least for home use, I like the alternative.
My opinions only.
