It's odd to say that I've been blown away by a company due to a potential serious electrical flaw, but hats off to Bambu Labs.
25th of Jan they got some limited reports about issues with the cable attached to the heat bed of the A1 3D printer (which I own). On 28th Jan they release a blog post explaining the situation in very clear language: https://blog.bambulab.com/a1-heatbed-cable-callback/.
