This VMR File has currently around 300.000 lines.
Compared to the most popular free one (that has around 100.000) lines, thats triple the percision for model matching.
Not 100% sure how to feel about this addon. I think for the use this gives (since public model matching already is pretty acurate) is pretty small for the price of this.
However, since there is probably still a huge amount of work behind, i can somehow understand the pricing. I still think more accurate model matching for this amount of money is just not worth - but if this is a very important part for you, then this is definetly a good choice and is working well.
