Question: Are there any vibration issues (as seen with other suction cup mounts)?
Document: Suction to the max! If you have a GoPro save yourself the trouble and get the suction cup mount. You will be so glad you did. This is one of the most versatile mounts in the GoPro lineup and will mount on almost anything. Don't be hesitant either. This thing will sustain high speeds on racetracks, freeways, you name it. Well worth the money!
Suction cup is strong! I like to fabricate mounts brackets etc or go with 3rd party companies to save that $$. This time  I wanted to make sure that the camera won't be moving around since my car is lowered and the streets of San Francisco is pothole central. Im glad I went with the official Gopro suction mount. This bad boy does not move at all!
I own 3 of these for my 3 GoPros. I attach them to my vintage Porsche 911 via the suction cup mounts. I've had it up to 120 mph, and the cameras held firm. I took advice from another post, and clean the area I plan on positioning the cup to with rubbing alcohol. Find the strongest you can get. It won't harm paint, but removes dirt, grease, and wax.
I tested out this section cup device on my BMW M3 and test at speeds in excess of hundred miles an hour. I had no issues with the product and I felt that it was solid and performed well. The only issue I have is that the product did not come with any type of instructions as it took me some time to figure out how to make the compression of the suction cup secure.
We haven't used it much as of yet, but so far we have had some issues with the suction staying power on certain surfaces when practicing with it.
I am always skeptical of suction cups BUT this one is hands down the best I have ever seen. This is hot all suction cups should be!
mounts works well. only complaint is the suction at times after pushing the suction button and locking it down  doesn't stick and i have to use my hand to press for it to hold. not sure if this is an issue at all but i know its not a user error since i have other mounts that work when i press the button then lock it in place.
With the long arms on this and long distance from the actual mount, there is way too much vibration on just about anything you can mount it too. The video is very shaky.
The only obstacle that I have encountered with this mount is vibration. I have not used the anti-vibration plug yet with this mount, but it is supposed to eliminate the shake. Other than that, be sure whatever surface you use it on is clean and dry. Have fun!
I've seen how they use these on the outside of cars and airplanes on TV, so I'm pretty sure it'll stay stuck on my stuff... ;)
Answer: I mounted it on the inside canopy of a P 51 mustang (1,500 hp) took off  did rolls, loops, stop turns, dives to 330 mph & 4 Gs  then landed. The entire 1 hr video was rock solid.
