Uh?? :-o I bought four of these cards since it appeared on the Amiga market.
Three was XSurf I and the last XSurf II, the first one in 1999 and the last in 2003.
It all fit perfectly in my Amigas (A4000 Desktop, A3000 Desktop, A3000 Tower, A4000 Tower) all in their original cases and without ANY modifications to it.
I've never have ANY problems with that four cards since and it are working nearly 24/7 here.
I will try it in some A2000s I have to see how it works.
As for the "slow speed" of it, it is known that the Sana II drivers are slower than their NMI counterpart, if you use Miami it's explained in it's docs ;-) speed is a question of cables quality and lenght too :-)
As for the "advertising", having a look at Jens' web site will show you it in all it's glory here :

If you want bigger photos you can go to

I don't know how you do when you want to buy something for my Amigas, but for myself I always go to the manufacturer site to have the more infos I can on that product before buying it.
