A lot of people are disappointed by the weight of the Sheath this time around. They added MagSafe, and that’s a good thing (although my non-MagSafe Sheath for my 12 Pro Max didn’t have it and still charged fine with the puck). But it’s the way they added it.
Instead of embedding the MagSafe ring in the case itself, they added a plastic insert to the back of the case that has the MagSafe magnets, adding a ton of weight to the case and making it less flexible than before.
While the new Sheath still remains my favorite case for my 13 Pro Max, it’s definitely a step down from the former design.
