I've had the cheapo ($5.96) AliExpress clear 360 magnetic stand case on my 10 Pro XL for about 5 days now.

It's a fine case. Fits great. Has small shock absorber bumpers on the corners. Cutouts are fine. Button pushes are positive and easy. I imagine this is made by a Chinese manufacturer that also makes "name brand" cases that are for sale on Amazon.
One thing they don't spend money on is their packaging. LOL!
Here's some more pics:
Time will tell how the hinge stands up to use. The magnet does not appear to be very strong. It will not hold the phone securely to the side of a refrigerator or the side of a steel file cabinet. The phone stays adhered to the surface but it slowly starts sliding downward, succumbing to gravity. The Pro 10 XL is a heavy beast, though. Not sure how many magnetic 360 case stands could hold the 10 Pro XL on the side of a refrigerator.
I have an antique Tylt wireless charger (5 watts!) that works with the case on. I haven't tried anything else that would use the magnetic ring.
When standing the phone up in portrait mode the stand is slightly wobbly. Again, probably because the phone is so big and heavy. Also, if you look at the part of the ring that contacts the table surface there are cutouts to help you pry the ring stand away from the phone's back. The result is the stand is really only using a couple of points to contact the table. It's more stable when in landscape mode.
There is a raised lip around the camera area to protect it. Also around the edges of the front of the case. The "G" on the back of the phone is centered perfectly in the circular magnet area, so no OCD suffering on that account.
The case itself weighs 41.8 grams. Usually I like my cases more lightweight than this, but, hey, $5.96.
There is no compelling reason for me to buy another case. But then, we don't really need reasons, do we?
