So, I see it performs as any other Prusa with a metallic frame. BTW, Al is better in this use than steel ! What about the cost ?
I said from the start, don't waste your time with an acrylic frame, get one with a metallic frame then improve it. Anet worshippers challenged that ! Funny isn't ?
OK, now you can start to improve it. Replace the LM bearings, get rid of the basic design error of the Z axis (I hope it is already TR8 lead screws and not M8, make a decent lightweight X carriage etc....

In fact, I think they should accept their mistake, keep the acrylic crap to play and move on to a better machine architecture and build, if they are serious about 3D printing.
