I like rack spots for every game except one pocket.
No idea if there is any trademark/patent/similar issue regarding Japan and/or Grace's import of the product.
As a consumer, I would say that the Slug Doctor appears to be the best implementation in the sense that it is so reusable and economical.
I showed this to the pool hall owner who imports rack spots from Japan and he told me that he had already tried the Avery labels (because they were less expensive) and that they didn't work as well as the rack spots. His comment was that the Avery labels were not holding the balls well enough with a single label. If he put two labels layered on top of each other it worked well, but then the label was a bit too thick (could interfere with play).
It sounded like someone earlier in this thread had indicated that these spots were used in a tournament or tournaments with great success. But now I'm not clear whether it was the Avery labels or the "real" rack spots product. Can anyone clarify?
They are very thin so I can understand what your room owner is saying. The SD resolves this problem by the close tolerances built into it that puts the dots in EXACTLY the correct spot to get the balls to lean in a bit. The thinness of the spots are a big plus in that they basically eliminate any interference with roll.

To call the Slug Doctor an imitation of anything is inaccurate at best and an ill-advised and lame attempt at sabotage at worst. Whoever invented the triangle would have a better case against the Delta rack. The SD is an appliance of original design for setting perforations available at any office supply store to a table that results in a perfect rack every time that is identical and equitable for both opponents every game.
The inventor of the Slug Doctor is an engineer by background and has designed other racking systems that have been successfully used in professional tournaments. I know him to be a lover of pool and by nature enjoys taking a project and engineering it to improve upon what he has seen out there. I highly doubt he is in it only for the money or he would have made it flimsier, developed a proprietary spot that alone could be used with his applicator and template, and only would have provided enough dots for one application, all to garner increased repeat business. I think the guy is a pool player who has found a way to contribute something of benefit to players, table owners, room operators and promoters – all at low cost. Frankly, we need more like him in this game.

JohnPT,the product is new but I’ve heard of no problems with several months of service and it is certainly possible they would only need to be replaced when new cloth is installed. If a dot or two should come loose it would take one or two minutes to replace it with the SD, no need to redo the entire rack or buy another rack.
