What have you guys tried, I just got a set of PgyTech and the gimbal would shake once you put them on. putting them on before or after power up makes no difference.

Thanks, Nice to know. The did offer to let me return them which I will but that would mean I'll have no ND filter for the rest of my trip, will see if I can find an alternative. If someone is using one of the other brands and have no problem, please let me know.

Yes, other brands should work wel.. i'm not sure but it should be related to the weight of this filter that is driving the camera crazy

I got the Skyreat ND Filters from Amazon.  I haven't used them, yet, but I tried them after your caution.  I installed the polarizer before before power-up.  Initially, my gimbal was steady.  I moved the Mini to different positions, and the gimbal held steady.  I put the Mini on the floor, and when I looked back at the display it was shaking.  I cycled the Mini's power and had no shaking.  In trying to recreate the shaking, I put the Mini back on the floor and decided the shaking started with the jarring I caused putting it on the floor a little too roighly.  I picked it up and then held the gimbal to stop the shsking.  It held steady.  I found that I could start the shaking by gently striking the bottom of the Mini while holding it.  I could always stop it manually .  I removed the polarizer and could not get the gimbal to shake at all. Going forward, it will be something to watch.

I've found it from PGYTECH:
