Spin Art Machine for Kids - Variable Speed Battery Operated Paint Spinner with Splatter Guard | Includes Washable Paint, Art Design Cards & STEM Craft Kit | Perfect for Birthday Gifts, Classroom Activities & Creative Play

I bought this for a friend with Alzheimer's who can no longer paint. She was delighted to be able to create something colorful again. Then my four year old grandson saw it and was delighted as well. So I'd definitely say fun for all ages. Seems to be of good quality and comes with a generous supply of carton and paint.The first time I tried the square paper it didn't seem to fit and flew off the spinner. After having ordered paper and paint refills, I tried the square paper again and it does fit. The trick is to put the corners of the large square paper into the outermost catches, or the four corners of the small square paper into the innermost catches (which at first I didn't even notice). It's a little fiddly compared to fitting the round paper, but once you get it right it stays in place, and it gets easier the second time around.
