I’ve tried the generic Grip Case, the Dbrand Killswitch, and the Jsaux Modcase grip already. And while they are mostly great I feel like they are all too bulky and interfere with the great original ergonomics. This setup keeps my XAX slim and doesn’t alter the original weight and feel too much. It also provides some scuff/scratch protection and I personally like to look of the skins and the additional grip texture is nice for long gaming sessions. I like having the device as slim as possible while gaming and I use the Tomtoc travel case for some additional protection when carrying it around or traveling. I also keep all my accessories in a smaller Tomtoc electronics travel bag as I use these accessories between this and my other handheld devices so I don’t need a big bulky case filled with accessories for each devices I just bring my one stop shop accessories bag shared between devices. I am also using another Baseus 67w USB-C charger and cable when I have it charging instead of the original charger.
