I've had no problems with the 35A controller I bought from Area13 in late 2021 for my 2021 MiniST2. Nothing stopped working (both head and tail lights are fine), but I regard both the stock and "premium" headlights as next to useless, so I keep the "premium" one mounted as an emergency spare and put a Planet Bike light up on the handlebars.
However, I haven't heard of the controller-burnout issue and have occasionally turned on the "premium" headlight for extra daytime visibility a few times, but never for more than just a few minutes and I generally don't ride after dark.
So I don't think it'd blow up anything quickly, but for long-term use I hope to hear somebody else chime in.
