The description for this K&F Concept Clip says "[Widely Compatibility] The clip can be clamped on most smartphones"

I have a Samsung A51 (the older 4G model) with an otterbox case. There was no way to attach this without removing my otterbox case. Note that I have another phone lens ND filter with a clip instead of this screw mechanism which is able to attach with no problems with or without the otterbox. Speaking of without the otterbox, my phone was too thin for the clamp, having the same problem as the next device I tried it on below.

So I tried it on my Samsung Galaxy Tab S9. I don't have a case on it. Again, no luck. my tablet is too thin. The screw mount pad, when fully tightened, still doesn't touch the screen with almost a 1/4 inch gap remaining. I might be able to get this to work with a felt furniture slider pad, but that is not ideal.

Finally, I tried it on my Pixel 6. Surprisingly, I could get it to fit even with the case still on. I thought the Pixel camera bump would not work with this, but it is ok(though not an ideal fit).

So in summary, unless you have an iphone that they list, you're taking a chance on this one.

Brilliant mobile phone - tripod adapter that can even stretch my crazy wide Samsung Note including the case

For the price I paid, this feels like a steal!!! Excellent quality, very easy to use, very well built! Could not ask anything more from a tripod to be honest. I actually had to wonder why some tripods cost so much more.This takes pretty much any phone we have, Samsung S9+, S10, S10+, iPhone 8, Nokia Pureview 9, Samsung Note4 to name a few! Phones are safe and secure in the brace that screws on top of the tripod.I have recorded around an hour's worth of footage and phone did not move an inch. I am looking to get a heavier camera though, let's see how it goes.For my needs this is working a right charm!!!

This tripod is very light and packed in its case, it takes up little space

already had rings to use Canon FD lenses on my Mirrorless Samsung NX30 but I wasn't entirely happy with them... on a friend's suggestion I wanted to try them and I have to say that from a constructive point of view they are really well done . No mechanical play, the lens is firmly attached to both the ring and the camera body and not even the stop-down ring of the apertures (which allows you to set the aperture to the desired value) remains locked in the selected position. We recommend!!! Top shipping service (as always)...!

This is the best monocular I have used to date and would thoroughly recommend using it. Trouble was the smartphone attachment is useless for a Samsung Galaxy S20 and used for every phone of this size I should imagine there are a few! It's a shame as I really wanted to see how it would work. Surely keep the monocular as it's really very good for what I want. Bird watching, country walks etc.
Nice carry case which is useful as it has a shoulder strap but forget the instructions as they are for binoculars. Easy to use so you don't need them anyway.

Good resolution. Fast using Samsung S23. Decent range.
