I purchased a poolbuster Commercial Grade from Costco a while back. Costco drop ships them from Watertech. It arrived the other day and the packing slip says commercial grade but they sent me a standard unit. This could have been a fluke but I doubt it since they did it to me TWICE! I ordered one last year with the exact same mixup. Anyway, the units look identical (save a "CG" sticker on the body of the unit). Sure its Costco and you can always return it but what a PITA. I hate to think they're intent is to purposely send the wrong one.................
Check your unit to be sure its what you purchased.
