I really love the Thomann short scale bass, but the white plastic nut it comes with is really nasty and cheap. This nut is the perfect width for it.
I had to increase the width of nut slot with careful filing, but this nut is so much better and the bass seems to have much more sustain (I don't think it is just my imagination).
The nut iutself is quite deep, so whichever bass you need it for, it will require a substantial sanding down, but better there being too much which you can work with rather than too less.
The material feels like it is going to last, and from the sanding process to bring the heigth down, it comes across as a quite dense material.
So far, no problems, so I can highly recommend it.
