We had aquadots. They were fun for DD9 to play with, until I found out they could kill her!!! Now they have a safer version, but I refuse to buy them. I never received any refund or compensation for the product I couldn't use. We actually threw out all the dispensers and grids too, so I don't want to invest in this lousy company.....
I don't know how the new version is, but the old ones held together well if the design wasn't too spread out or made of single strands of beads.
