hey there! I use magsafe on my z fold 3 and love it, especially with how well the concept works with phones that change shape

https://www.amazon.com/dp/B09MDY421H?psc=1

here's the one i use, very strong

my favorite accessories are the car dock, wall mount, arm mount, and phone stand (self made)

So I purchased multiple cases seeing the mfg pictures online and couldn't decide which case would be a good fit.

I wanted a magsafe case as I just like the magnet idea for car mount. Makes getting in and out of the car way easier than traditional car mounts.

The magsafe mount I purchased is a vent style one, a pretty small footprint, as I don't really like huge car mounts on the dash or whatnot. It was fairly inexpensive. I had good reviews with magnet strength on amazon, so I ordered it to try it out.

Ciencimy Magnetic Car Mount... https://www.amazon.com/dp/B08SQPKQ14?ref=ppx_pop_mob_ap_share

It was $14 shipped with tax.

I purchased 4 cases listed above.

-Spigen Rugged Armor (no magsafe) was thinking of adding an esr ring on the back of the case.

-Torras Magnetic Guardian has a smoked black backing and comes with orange and neon green replacement buttons if you want to liven it up. Case has plain matte black buttons installed. Has a ring built into the case.

-UAG METROPOLIS LT Pro. Looks cool. The back has real kevlar padding but is expensive. Magsafe ring built in.

-mous aramid fiber limitless 5.0. Has magsafe built in as well. This one, I am still waiting for to see if how good it is.

So, after trying on all the cases except for mous case as it hasn't arrived yet.

-Spigen rugged armor: it is a basic case, I have used spigen on other phones, never had a huge issue as most of my previous phones were not a large and heavy as the S23 Ultra, decent grip, looks ok, but not mag safe. The backing is kinda texturized, so my plan to slap a esr halo ring on the back will not work. Fitment is typical spigen, decent all around, it isn't special or amazing, sides are ok not slippery but not grippy either.

-Torras Magnetic Guardian: I was thinking this case would be horrible but gave it a chance, has almost everything I want in a case. Fitment is good, looks ok, has a haloring built-in, so the back is nice and smooth, extra buttons are nice, and it's reasonably priced. I wish the camera cutout was not as open, but it is workable. Case feels pretty good in hand, not slippery. With the phone in the case, I tested the car mount, and it passed the pretty aggressive wiggle test.

-UAG Metropolis LT Pro: Had high hopes, decent looking case, magsafe built in, camera cutout is spot on, phone is snug fit. Where this case fails for me is when holding the phone. It is very slippery. Phone just slides through my fingers, esp with the heft of S23 Ultra. The case also did not pass the magnet wiggle test. The kevlar padding is rather thick and prevents a solid stick. I would barely move it, and it falls off the magnet.

-Mous case: waiting on case.

It appears that for now, I will stick with the Torras case as it has surprised me. It is not perfect, but it checked enough boxes so far.

Sorry for the long post. Hope this helps anyone out. I'll update it when I get the mous case in.
