I was so excited to finally get these for my boys. However, the first time we got them out I noticed that they wouldn't stick to any of our tub area surfaces. I tried the tub and the tile around the tub. I tried them dry, wet, and soapy to see if that helped. The smaller ones stick to each other well, but the large ones are crap. One of them already has a split in the suction cup, rendering it useless and leaving me to wonder how long the others will last. The only reason I gave this product 2 stars is because they make good baby chew toys.
