Yeah I got a set. They're just as good of quality as the OEM Mtech mirrors, the only difference is the aftermarket ones have a wide angle feature which is kinda cool once you get used to it. I think they're a little quieter than the stock non-mtech mirrors too. One thing I suggest is reusing your triangular rubber seals off of your old mirrors. The seals provided with the aftermarket mirrors seems to be softer and less resistant to the elements as the original seals. I reused mine, they fit perfectly.
