Custom Review of the Galaxy S24 Ultra slim case with magsafe ring

5.0 out of 5 stars Great case and strong magnets Reviewed in the United States on February 9, 2024Size: S24 Ultra with Ring Stand Verified Purchase

"This is a great fitting case, and texture on the sides is a good addition. For a clear case finger prints showing up are not terrible, but are a little noticable. Magnets on this case are freaking stong. Does not effect the spen as the case itself, but haven't tried with any magsafe attachment yet. But my wife's s22u has a magsafe case and with anything attached, her s pen has an issue as well. I think magnet cases effecting the s pen have been much more voiced with the s24u, and is getting blown out of proportion. Cases may have magsafe magnets, but I don't think device was ever really intended to be "magsafe" compatible.

Case if very well fitted to device and is nice and rigid around the screen. A little weary about the case only extending about 1mm past the provided screen protector and only on the top and bottom. Back is very smooth and does not offer much grip, but wow does the phones brilliance shine through beautifully. Buttons are still very clicky and cutouts are all spot on. Camera protection is great. Case extends about 2mm past the cameras and provides a completely flat back, not more rocking while on the table. The detent to hold the ring/kick stand is strong and should have no issues keeping it held in. Also hinge has good traction to keep the ring held into almost any desired position. Not much padding on the corners, but there is an air gap, so drop protection is provided, but am not one that wants to test that out purposely.

As I work industrial maintenance, this won't be my daily driver as I don't want it to fall out of my pocket. But days off, for sure as case and phone combo look fantastic together."

Wrap up:

It is important to find out what kind of style and protection you need daily. When choosing a Galaxy S24 Ultra Slim Case, remember that the "best" case depends on your needs. Whether you prioritize ultimate thinness, a no-slip grip, or a balance of both, this guide offers a starting point for your search. Do further research the cases mentioned based on what matters most to you, and you'll be well on your way to protecting your S24 Ultra in style!
