The cover is undoubtedly an excellent product, well made, easy to insert and remove, the silicone is soft, not too thick, it does not emit bad odors and above all it does not attract dust thanks to an effective surface treatment, and there is also a fantastic lens cover that is very comfortable to protect one of the most delicate points of the Go Ultra.
Like all accessories, it has positive aspects and others to evaluate based on use, obviously it is not essential, given the good resistance of the chamber, but in my case I chose it because, using it on a motorcycle, there is a risk that it will be hit by pebbles.
The quality of the mold is excellent, the microphone holes and status LEDs are precise and well aligned, the only slightly delicate point is the silicone thread near the right hook (visible in the photo).
As for the use in the action pod, in my opinion it is not suitable, the contacts remain free and functional, but due to the thickness of the silicone there is no mechanical attachment to the side safety blocks, personally I would not trust using the camera in the action pod held only by magnetic force.
Another aspect to consider is heat loss, the Go Ultra, like all action cameras, tends to heat up a lot at high resolutions and frames and a tight rubber cover certainly doesn't help with cooling.
In conclusion, an excellent accessory to use in case of need or for extra protection, while I find the lens cover really comfortable and practical even on its own, without having to assemble the entire cover.
