It works as intended but I didn't get the allen key in the box to remove the tripod mount and despite contacting K&F about this I've had no reply otherwise it would have been 5 stars.
Update...K&F did finally contact me and are sending out the tool to remove the tripod mount so have increased the star rating accordingly

I have tested this on two cameras, an EOS R and an EOS R7. Both cameras have the same issue this adapter. After taking a few shots, powering off the camera, changing lenses, and then powering on the camera, the camera does not respond as of there is no power. The battery is fully charged and I have tested with two other batteries with the same result. The item itself seems well-made although the mount side of the adapter for the lenses is somewhat tight.For some reason, communication between the camera and this adapter gets lost.
UPDATE: I received a message from K&F customer service. They were concerned about my issue and replaced the adapter with a new one that functions far better. Not only that, but I want to point out that their packaging of the product is great, much better than most sellers. Their customer service is excellent. It's rare these days to receive such personalized service from a seller. They respond quickly to my messages and kept me updated as to the shipping of a new adapter.

It does what it says at less than half the price of the canon equivalent.
It occasionally seems to stop ‘passing through’ when changing lenses. I’ve also experienced strange focus issues when moving from landscape to portrait, I’m not sure if this is true of all adapters or the way I’m using this one. When you’re aware it’s a minor inconvenience to deal with it if it occurs.
Worth the money if you’re not changing lenses or for occasional other lens use.

The K&F EF EF-S Lens to RF Mount Adapter has worked perfectly I just got a new Canon R6 mark ii and have been able to use all of my EF & EF-s lenses without issue, the photo quality has been great. All of the features and functions work as expected!

It is quite a tight fit, so much so that I felt nervous mounting the adaptor onto & off the lens the first couple of times. Mounting the adaptor onto the body wasn't too bad. I guess it will get easier over time but I am prepared for having quite worn-looking barrel mounts on my EF lenses.
All that aside, it does an excellent job adapting my EF lenses to my RF body, all camera/lens features & buttons work natively.

Out of this box this feels solid. Connects to my camera body without issue and works pretty well from what I can tell. I only have one older lens so I havent done extensive testing on this but what I have works like a charm so this is great. Cant wait to expand my lens collection and put this through its paces. Very happy with this.

If you want to just be able to adapt your beloved EF mount glass to your newer RF mount body, then this is an excellent option. The autofocus was fairly good and the adapter seemed to function well. I dont own any third party EF glass so i couldn’t say if this adapter will play well with them. What i do know is that this adapter works almost as good as the more expensive versions on the market at a fraction of the price.
The only issues that i noticed with this adapter was with full time autofocus in video. It seemed to stutter a bit more than i noticed with the Canon adapter. As long as you are using this for portraits and landscape, then this adapter will work perfectly fine.
