This K&F frame for the GO Ultra for less than ten bucks is one of those accessories you buy out of curiosity and then you don't understand how you've lived without it. Look, I used the GO Ultra basically with the pendant and the cap clip, and I was delighted... until I realized that I had a mountain of GoPro holders laughing dead in a drawer. With this frame, the capsule suddenly fits into any GoPro base, any tripod, selfie stick, suction cup, chest harness, whatever. And on top of that, it comes with the 1/4” thread adapter and the screw, so ready to use as soon as you take it out of the bag. The plastic is decent (it's not the official Insta360 cage, of course, but for ten euros nobody asks for wonders). It weighs practically nothing, it fits perfectly, it doesn't dance a millimeter and the best part: you can open the microSD cover without removing the camera from the frame. That's pure gold, because with the official one you have to take it out every two by three. For quiet things, the magnet is great, but when you ride a bike, run or do anything a little more gross, this gives you peace of mind that the magnet doesn't give you. The camera is fixed and fixed, there is no risk of it flying off the first pothole. The only thing that still bothers someone is that putting it on and taking it off takes ten seconds longer than the magnetic click, but come on, for that extra security I think it's a ridiculous change. As I said: for less than ten euros this is an absolute no-brainer. I always have it on when I go out to record something minimally moved. If you have a GO Ultra and you don't have one yet... you're taking too long. I think it's the best thing I've bought in a long time for the camera. 10/10, I would buy it a thousand times.
