HIGHLY RECOMMENDED. One year and another baby later, these are still a favorite for many reasons.Boon Jellies span a wide age range. Throughout the last year my son had varying interest levels with them. However, it's always a toy he comes back to, which is very rare for him.As my almost 3yr old gets older, he plays with them in new ways. I have a 1yr old daughter who loves to play with them as well. Aside from the versatility of stimulus in play they provide, they are very well designed and made. They are really beautiful toys as well, which is so rare.I'd like to address a couple issues I've seen people post about. Mold. The only way this possibly will build up mold is if you leave water in the cups for extended periods of time (over and over)! User neglect, not design flaw. They are virtually impossible to give rise to mold if they are drained. I leave them in the tub for a couple days as long as the water is drained from the tub the water in the toys always dries out, and I live in a very humid area. Or you could just do the smart thing and put them away after you use them. Unlike toys that are closed and difficult to drain these don't hold water if you just take one second to put them away; thus, you'll never have mold.The suction has not decreased over a year of use. We occasionally leave them stuck to the wall for a few days at a time. The only suction issue was with build up of minerals from the water on one of the cups. Used a toothbrush give it a quick scrub, good as new sticking to each other again.My son likes to play with his toys rather violently, these have held up to many many throws against the size of the tub.Generally, my son does not like popular toys. 9 out of 10 toys I've gotten for him he's wanted nothing to do with. It is nice to see such a beautiful, sturdy, versatile toy that has stayed in use for such an extended period of time. My daughter conversely loves 9 out of 10 toys she gets, she loves these too.If I am too exhausted to put away these toys at the end of the day they still look cute in in my bathroom, instead of a eyesore.Win Win all around.
