Yes, Manuel makes a VERY high quality product. I have the Elise version. It's extremely nicely made. The Emira's shifter is far better than the Elise's was, so I'm not sure if there's much to improve. But there are some provisions for adjustment of the shift throws as he did with the Elise. It's also important to note that his customer service was excellent. He's very helpful in answering questions before and after purchase.
You can see the Elise version in a little more detail here.
