The resin works great. I get better prints from the black than I did from the grey that came with the printer. Instructions on the bottle say to shake well. So I did, and the resin came spilling out even while I was removing the security seal. The cap evidently does not seal the bottle at the top, but only at the lower rim. DON'T SHAKE THIS BOTTLE.

Poured it into the printer, and it stop printing. Prints would no longer stick to the build plate.

Overall this resin has a great amount of potential, but did not end up working for me at all in the end.Presentation of the resin is stellar, 5/5 on the nice aluminum bottle and informational Monoprice sticker.Functionality this resin gave me issues off the bat, fine supports were failing and edges were warping and not coming out straight.Cleaning was a hassle. After 20 minutes in an ultrasonic cleaner, an alcohol scrubbing and over 12 hours of cleaning, the finished piece would not come out clean and remained sticky and tacky. With that being said, I was expecting more from this resin as the initial unboxing looked very promising.

Every print I did with White turned out good. Mostly small gears.

I have had several fails with the Gray. I quit using it.
