Squigz Toys Official Reviews 1

Bought these for my 3-year-old and he's been playing with them almost every day for the past two months. They stick well to smooth surfaces — tiles, glass, bathtub walls — and the suction is surprisingly strong. Love that there are no small parts and the silicone feels safe and durable.
The reason I'm not giving 5 stars: a few of the pieces don't stick as well as others, especially the smaller ones. Also, they don't work on textured surfaces at all, which limits where the kids can play with them. And for the price, I expected a few more pieces in the set.
Overall though, it's a solid toy that actually keeps my kid entertained without a screen. Would recommend, just go for the bigger set if you can.
