The jury is still out on these in this house. I do like that they stay wet for so long and that I can dry them w a hairdryer when I'm ready. I do like that when they are dry, they are tough, like regular acrylics without sealing them.
But there is a lot I really didn't like. Keep in mind this is after one session of play.
They stay wet for a while, but "set" to a strange consistency right away - after the water evaporates. Once they are in this stage they have a really odd "pull" to them that I didn't like at all. Not tacky, exactly, but gooey. Glycerin-like.
They are exceptionally translucent and you need to use a LOT of paint to get any real covering power. More than other acrylics I've tried. I only used Titanium white and burnt umber on this. Other colors to come next.
Right now, I'm leaning toward the Atelier Interactives, I can let them dry right away, or keep them open with water (or slow drying medium) or open them later with water. They aren't the most potent pigments in the world, but much stronger than the Golden Opens of the same color. I suspect it has to do with the whatever vehicle they are using to keep them open.
More play is needed.
