Maybe the price was just too good to be true. I'm still waiting for a refund OK on this one. The build quality looks pretty good for the price. The Z axis control worked during setup but failed after the first print (or from the looks of the print, halfway through it). Getting enough tech support to fix that kind of problem proved to be hopeless so I sent in a return request.

This is great resin, works well with Monoprice new SLA 3d printer. Great price and the bottle is well made, seals perfectly, and is easy to pour resin into printer vat.
