First of all service from Coffee Addicts was fantastic. They managed to get the part much faster than expected and they were a pleasure to deal with.
The part is great but not as pictured. The black plastic top and halfmoon stop adjustment are not part of the package. You get the brass burr carrier with new burr screws. The rest of the parts you need to re-use from the old carrier. Which is not an issue. I used this part to replace the original all aluminum carrier that developed damaged threads. I used a tap to clean up the threads in the grinder body and installed the new brass carrier. It took longer to dial my grind back in .
