great idea for a nozzle cleaner, simple construction, high quality workmanship, but the tension is too high for the MIG nozzle cleaning routine. The tension that is too tight makes using the cleaner more awkward than just using a MIG gun (IMHO). With manipulators that don't clean their nozzles until the hole is closed you probably need that level of tension, but then if it's so clogged you'll never get the cleaner down the hole to use it.
