Carbon Can Co. - any good?

Peeps,
I'm trying to get legal cans for my 900ss and having all sorts of trouble.
You see it's a '96 model and everyone seems to think only the injection models exist and you only want race cans.

Now i've been "approached" by Mr North Yorkshire plod previously for a full race tune and Yoshi on a Zephyr550.

So i've found the Carbon Can Co, definitely do road legal cans in a vatiety of shaps and materials for a not unreasonable price.

The big question is, "are they any good?"

So if any of you have any experience good or bad, please tell me before i go spending my hard-earned cash.
