Exact same here. Moved from the Spigen to the JSAUX with screen cover. Absolutely recommend the JSAUX modkit, it may be my end game deck protector (so far).

For cases, I moved from the pack in to the Gen 1 JSAUX about a year or so ago (the ability to store a Anker Powerbrick + wall wart along with some wired buds and USB-c cable was great). That was perfect until I picked up the docking station and wanted to pack that around too…

Currently I have the Large Capacity Case and it’s working great, but man, this thing is unwieldy in a backpack. That said being able to have all of my Steam Deck shit in over spot for trips is pretty awesome and I throw it into a carryon more often than not if I’m taking the whole kit.

Usually though, I’m rolling with just the deck + modkit with screen cover and power pack in this sling bag. Seems to be the most efficient solution so far, as I don’t really need all the extra stuff in seat when I’m flying so it just gets packed in to my checked bag.

Apologies if this sounds like I’m shilling for JSAUX, it’s not. I legitimately have found them to offer the best solutions when it comes to what’s on the market for the Steam Deck currently. Both myself and my partner use their covers and cases, as does my kid.

My only note for improvement is on the size of the large capacity case, but honestly, I don’t think there’s much that could be done to retain capacity and protection. It’s just the nature of how big these portables are going to inherently be.
