I have it for about a year with Mamiya M645 35/3.5N and 120/4 macro. First let me say that it is the only adapter of its kind so if you want to turn your Mamiya M645 into TS ones you simply must buy it. That said, it's a very good one. It has its pros and cons like every product but in the end, the pros outweigh the cons. Search the alt forum in FM and you'll find plenty of threads and posts.
FWIW, here are some of my tilt pictures.
