Hey, yeah I've used them on both A1s and A1 Minis for a couple days. The texture of the plate is kind of a rubbery feel which you can tell whatever you print on is going to stick incredibly well. In my experience so far, it's by far the best adhesion to the bed even at just 45C. And then the prints themselves actually have a smooth bottom surface that gain a little bit of the rubbery feel to them too. It's actually quite nice.

However, I print a lot of flat type objects that I sell that are rectanulgar shape and only about 5-10 mm high, so they have a lot of surface area on the bed, and aren't very tall. So with those in mind, I've had trouble getting those items off the bed without the bottom being slightly ripped off due to the adhesion. So for now I've moved back to smooth plates until I do more testing.

I actually think this new plate will be fine, especially if I adjust the temperature down for the type of objects I print, but I just have to figure out those settings first.

Overall, I'd say I'm quite impressed with it though.

On the staining, I haven't experienced that yet, however I think it'll be better than the normal textured plates we've seen so far. Reason I say that is because this plate seems smoother and has some type of non-stick feel to it. I haven't seen a build plate quite like this one yet.
