Perfect replacement in minutes for 2016 C300
This was a perfect replacement and took minutes to install in my 2016 C300. One side of my button had broken and I was easily able to remove it completely (without removing anything else) by pushing the button forward and using a very small screwdriver to detach the unbroken side. Once the old button was removed, I removed the spring and tiny paddle and then used a vacuum to remove the broken piece and made absolutely sure no stray pieces were left. I then replaced the little spring + paddle (the new one came with these parts also) and easily snapped the new button in place. Note: Once installed, it does illuminate the same as the other buttons. I dreaded even asking the dealer's price to repair this and this was an easy fix for $15.

color just a tad off but still a good deal
The color is just a tad off from the factory thus the 4 vs. 5. For the price worth it. This went into a 2020 c43
