I have a GS bag on my GSA. After 3-4 years it is faded. The main access zipper has crapped out. I plan to get the zipper replaced and use the bad some more. I want to get the newer EVO GS to replace this, but I went and bought a nice used BMW GS bag that has the old stretch band crappy mount but look pretty and now I'm invested on that for a while, but will probably use the Engage bag again once my local luggage repair/shoe repair guy puts in a new zipper.
The mount system works great, as intended, a bit stiff to get on and off when overstuffed as it always is at gas stops, etc.
I tried the electrical ring, but screwed it up when I though the relay wasn't working, and i don't think the little pins are worth much. I now have an SAE wire coming into the bag through a powerlet port and that works great for charging lots of stuff at the same time, like iPhone, iPad and even my Sena when it runs down which is never.
Normal is just a setting on the dryer.
