  1. Maria

    My daughter is obsessed with this toy! We got it when she was 6 months and she still plays with it every day at 9 months. I even bought one for my niece!

  2. Sarah B.

    Got this for my teething baby. It’s really cute. I thought when I purchased it that the rings were all solid plastic, but the three solid-color large rings (not the one with beads) are thin plastic, and pretty flimsy. They may not survive teething infants. The small rings are solid and of course the ring with beads is a favorite. Overall we like it, just not exactly what I imagined it would be.

    I love the textures and designs to these rings. I hate the fisher price kind that every baby has. These are more unique and help with teething! My daughter loves them so much.

  4. Denise

    My grandson loves this toy!! The colors are so vibrant and beautiful; they are so appealing to him. The rings are all different textures; one is a rattle, a few are teething rings, some have texture, etc. she hasn’t yet used it for actually stacking, but I can tell that he will be doing it in no time. He loves playing with us and is drawn to the colors and vibrancy of all of the rings. It really is a wonderful toy.

  5. Tate’sMom

    I thought this would be a great toy for my nine month old twins, but they didn’t seem interested in it yet. It’s smaller than the usual stack up ring toys, so it was a little tedious for them. I’m sure that soon it will capture their attention soon.

  6. Meghan

    My one year old absolutely loves this! She uses them as teethers and bracelets too. They don’t show bite marks and the color doesn’t come off. It’s super easy for her to slip the rings on and off the cylinder.

  7. Carmen Lewis

    It’s a classic for a reason! Our 10-month-old loves this toy better than most of her others – even the flashy battery-powered ones! She taps the rings together, uses them as teethers, dumps the stack, and is finally figuring out how to stack the rings. Overall a great toy to teach cause and effect + problem-solving. My only issue is that the stacking portion of the toy is so light that it falls over if there are not a couple of the bigger rings threaded to stabilize the base, which was a little frustrating to my daughter when she was trying to learn how to stack. It was not a big enough issue to deduct a star over, however.

    Baby likes to throw the rings off of the high chair so Mommy and Daddy will get them for the baby.

  9. Elliot’s Essentials LLC

    The nursery at our church has this in their toy bin and my 1 year old loves it so I got one for home. I had a much larger version for my eldest when he was a tot and I find this one to be much easier to handle. This is the perfect size for fine motor development. The rings are different sizes, color patterns and textures. They can go on in any order which I love. The other version has a slanted base and the rings must be placed in order to fit. This is one of my favorite toys. Points for style, size and sensory.

  10. Monika Lobbell

    My 7 month old son’s favorite activity with toys that come together like this is taking them apart. Stacking cups? It’s a race between me stacking them and him knocking them down. Shape sorting box? I can get maybe three of them in before he rips the lid off and spills the pieces everywhere. And this stacker? Forget it! His favorite part is the middle stack part, he loves taking all the rings off and using the middle part to swing around and bang on the floor or other toys. He loves chewing on the rings, too. I thought he’d be really interested in the fourth ring, the clear one with the beads inside, but he doesn’t really care for that one over all the rest. Overall a great toy and gets used daily in our house.
