Tape is tape regardless off the quality it will always just be tape. If there were
such a thing as superior quality tape then maybe other parts of the gti would
be put on with tape. Oh well good luck selling them.
Well, I ran these paddle extensions on my Mk5 for well over a year, including 2 track days and an autocross. The tape is more than adequate to secure these to the OEM paddles. In fact, I am running them in my Mk6 and fully expect years of trouble-free use.
Looks are subjective (I like them, others may not), but they can take the abuse of daily use and laps around the racetrack, even if it is "just tape".
