My son LOVES this toy,
Verified Purchase(What's this?)
This review is from: Battat Sound Puzzle Box (Baby Product)
They have a few of these shape sorters at my son's nursery school. All of the kids gravitate to them, from ages 8 months to 2 years (the younger babies don't seem very interested). My son (who is 14 months) spent a good hour figuring it out, trying to sort the shapes over and over again. I finally found it on amazon (I wish they'd put shape sorter in the title!) and jumped on it. What's different about this sorter is that once the kid gets the shape in the right hole, it makes this super weird, cool sound as it floats to the bottom of the tube. The babies think it's hysterical (and so do I). There aren't too many shapes (3) so it's not super frustrating for them, and they like turning it over to get the shapes out (which also makes it into a sort of rattle).
This is by far the best shape sorter I've purchased so far (and I've purchased a lot of them!!!). Highly recommend.
I wish they'd sell the shapes individually. My son plays with it so much that we inevitably loose the pieces... So it'd be nice to have some backups.
