Im giving it 4 stars because it does work however its not perfect right out of the box. There's an issue with the surface finish.. believe it or not its too good. The aluminum plate is highly polished (with the exception of the etched grid lines) and the resin struggles to adhere to it. I tested the same print using a BIQU flex plate and it worked fine. After examination i noticed the BIQU plate has a much heavier brushed finish. So using the reverse side of the liquid models plate, i sanded it with some 800 grit sandpaper, cleaned it off with alcohol and prints came out perfect. 100% will buy again if i need it but cant justify 5 stars as it wasn't use able straight from the box. Also for anyone curious to know - versus the BIQU plate i've found the Liquid Models to be superior in magnetic adherence and flexibility. The BIQU is slightly thinner and i find bends off the magnetic strip fairly easily - one of the reasons i've stopped using it.
