Works very well. Easy to use.
With this tool, it's very easy to code lenses for the Leica M-system. Works well. Easy recommendation.

Works great! Really glad I purchased this.
This tool works great and so far all the codes have worked pretty much flawlessly. Saves a little bit of time when you attach a non-six bit coated lens for sure would recommend to anyone that has non coded lenses

Overpriced and not as expected
The template is pretty nicely made, but the edges are too thick which causes the code to be weird, and the supplied pens just rub off the metal on the lens barrel.
