Strange... I wonder if there are any other members having issues with those ND filters.
Keep us posted!
They came back very quickly and said...
We haven't heard this issue of shaking with any buyer expect 2-3 where it was an installation issue.
If you are having the shake mostly probably there could be 3 reasons as follows.
1. As you know Mavic Mini filters are tiny so installation is very important if they are not installed properly you will have the gimbal shake so please do check if the installation is correct as that's where this issue comes 99.99% of the time.
OR
2. If you are having this problem with one the filter in the kit which could be our filter problem, So please give try to other filters to see if this happen with one of the filters or all the filters in the kit.
OR.
3. If you are having this problem with the ALL THE 4 FILTERS in the kit even after proper installation which means your drone have tolerance issue what is tolerance issue take for example Mavic mini gimbal tolerance is 1.2 grams meaning up to this weight the gimbal will perform ok our filter is within 1.05 but in 10,000 thousand drones are made some will have less tolerance than others meaning their tolerance maybe just 1 gram or 1.05 grams in that situation you will have an issue with all the 8 filters we have noticed this with the past drone of DJI but so far with Mavic mini, we haven't heard this but it is possible.
So 99.99% it could be the installation issue so please give a try & try some other filters in the kit.

I'll give their suggestions a try and let you know how it goes.
