I used this to remove the air vents on my 2018 GLA. That works great. It's well built and a quality tool that mimics the much more expensive OEM version but maybe even better as the handle is more comfortable and offers a better grip. If you try to use it, follow the same instructions as for the OEM tool (which has the same disadvantages): make sure you hook it in the right place, tighten. very hard, make sure you secure the device with both hands so it doesn't fly away and make sure you put your finger on the tool in the vent so it doesn't move and scratch the inside of the vent. It's inconceivable why Mercedes might not understand a better process, but this tool gets the job done at a good price. Bonus - now I have two of these. I probably won't need it anymore either :)
