I shorted out the original bed (almost started a fire!) so needed this replacement. Good communication from the customer service team - they responded quickly to a question and shipped reasonably fast. This board has soldered connection points which is not a problem, but I was hoping to just screw in the terminals of the new board without having to open the enclosure for the Prusa MKs3 board - so was not able to do this just FYI. But it was easy enough to install anyway.
The included power wires are considerably stiffer than the standard Prusa wires; I'll assume this will not be an issue but it could be an indication of lower quality or a potential repetitive strain failure in the future.
My first impressions of the performance is excellent. I got some of the nicest and trouble free prints I've had with this heatbed and the included plate which has a very fine texture (I did change the nozzle for the first time in a while FWIW). Overall this is a great value for the price. Happy with the west3d store and the heatbed/plate.
