As you have seen there are three perhaps four different types -- mesh, lighted, unlighted, strapped, etc. you get the idea. I believe each one of these has advantages and disadvantages for each indivudual. Perhaps each owner would give you the pros and cons of their diffuser. Since I have the mesh I'll start with that.

Pros: Looks factory OEM, shares the design used with the BMW and Porsche. Works great. No restrictions on vision.

Cons: Cost.
