I fitted this to my Neff C17MR02N0B combi microwave and B57CR22N0B oven. Easy to install, just follow the instructions.
Gets marked down slightly as I encountered an issue with the bottom oven. It wouldnt go into pyrolytic cleaning mode and threw up an error code as the door wouldn't lock. On closer investigation the locking pin was hitting the edge of this trim which was preventing it from moving to the lock position. I removed this trim and installed the original one that came with the oven and it worked fine. I then filed a small bit off of this trim (I'm talking a very small grove, 1 - 2mm, but it was enough to stop the lock pin from engaging) put this bit back on and its all working fine now. A bit annoying but no big deal but something to watch out for if you encounter the same issue, I was worried the oven was broken! It must be a slight issue with the manufactuing tolerance, I can't see that it would have been installed incorrectly, it locates in 4 screw holes so it either goes on or it doesn't no wiggle room.
Other than that it looks great and is a nice addition if you have more than one Neff appliance to make it all look a bit sleeker. Just make sure it fits your appliances first as I dont think it works with all of them.
