I know not many people had been able to get their hands on the Stylthgrip yet but maybe they’ve started shipping? The two look obscenely similar so it’s hard to gauge which might be the better one.
One thing that I don’t like about the Killswitch that made me choose the JSaux Modcase over it is that you have to remove the charging cable when putting on the front cover. Can’t see by pictures if that’s the same with the Stylthgrip, but it’s a small QoL feature to consider when choosing which car you want.
Ours allows use of charging cables with the cover on and also lets the Deck cool properly when attached.
I’ve just got the stylthgrip and it’s honestly very good. The grip made a significant difference to the weight distribution.
However, I have disliked the cover that clicks on. It’s hard to get on and off. Maybe I’ll get used to it.
