This resin is awesome! It prints easily, products come out nicely with great detail, it's super easy to clean up, and there are little to no VOCs released (I know because my dog is very sensitive to irritants and will begin coughing if any are present, and he doesn't cough when I use this product). It's better than Siraya's and doesn't contain benzophenone (a potential carcinogen) as a photo-initiator. It also smells much better / carries a weaker scent, but when printing with a heated chamber it can release more scent than usual (still less than many other resins). The scent is less alcohol like or more like a light glue.
