Things I liked:

Fast shipping.

Things I would have changed:

This is a strong DO NOT BUY review.

What others should know:

I bought this for a fairly new HW30S. Read the other reviews and knew there would be a 50/50 chance of being disappointed. I was. Tooling marks, chips in the aluminum, and the bluing looked like it was applied with a broad tipped Sharpie dry erase pen. I quickly realized that it would take a lot more effort to make it fit than I was willing to try, especially since it was such a poorly made item. What ever happened to the old HW brakes that looked as good as their guns and fit like a glove? I’d gladly pay double the price.

Things I liked:

This fits a FWB 300s very well.

Things I would have changed:

The set screws need to be filed down a bit so they do not stick out so much.
