I don't get it, but kids LOVE these things!!

We've had a ton of items that grow bigger when submerged in water before.  There's something about these little guys who hatch from an egg that my 5 & 6 yr old go nuts for.  I put them in their Easter baskets and they are still playing with them in June!!  When they get small, they put them back in the water to grow again.  I think they're laced with kid crack...

Kids were not that interest in these UNTIL I told them how to scare there mom and dads. Then all the little kid hands (ages 9-11) began snatching them out of my hands!  Kids ended up loving them. As with many toys - it's all in the presentation and excite level the presenter can generate :-)

I really do not have any comments.  I would be concerned giving them to younger children.  They may be a chocking hazzard.

They're certainly not high-end; the purple one didn't ever work, and the others just wouldn't go in a straight line. After about 4 or 5 minutes of trying to play with them, my guys all gave up and never tried again. Maybe these would be good for a very young child who is amused by the cars just spinning around in a circle for 2 or 3 seconds...?

They are so small that they look like kids toys. Haven't used them yet but will see how they work. may be surprised at the small size.

When opening, my first impression was that they appeared very cheaply made, but they connect very well and keep a strong hold. My four year old daughter and 9 year old son both really enjoy these.

For those reviews commenting and lowering the rating because there are no directions, please be a little creative! Use some imagination! These are meant for creativity. Kids should not need to always be told what to think and how to think it! Kids need to have a vision and make it happen; that's what these, and legos, are made for. Am I the only parent that throws away lego directions?

Hot item at elementary schools right now, but I'm not sure why.  Kids love them and that's all I know!

Yep, the kids love these things.  12 yr old and 13 yr old boys.

They do all kinds of tricks with these.  I don't understand how to do it, but the kids do great.

it's definitely not a WOW kind of toy. They r very similar to the sock em boppers robots.. It was a gift for my 6 year old nephew who specifically asked for these by name. He was not as excited as I thought he would be. First of all the toys did not come in a manufactures box with the pictures, clear plastic, ect, instead it came in a brown shipping box with Amazon brand on it and the toys were wrapped in kraft paper. It took a while for the other moms and I to figure out how to put them together. They snapped and slid into place, my 6 year old nephew wouldn't have been able to do it. Overall they are colorful and chunky and cute and once we got them together the kids played with them for about 5 minutes and then they were over it, lol.

Don't think about it. Just buy these things. They're awesome. They keep my kids occupied for hours and even captivate the grown ups. This was the second set we purchased because we didn't realize how big of a hit they'd be when we bought some at Christmas. There weren't enough to go around!
They are fantastic. This brand, in particular, is great and durable quality. I highly recommend the big red platform thing that you can buy separately. It's not necessary for building awesome things but definitely adds a layer of fun!

The bigness make them fun.  I found equally big and interestingly shaped wands at the dollar store recently.  I'm sure they are both the same cheap made from China caliber.

I work in a preschool and my students LOVE these things.  They can be hard for the little kids to wind up by themselves but they keep the children entertained for a long time.  Also, as an adult I think they are pretty darn cool and not so loud that they drive me crazy.

People buy things, and they don't bother to read the description provided by the seller.
The picture is to show you that the styles vary. It states RIGHT under the picture:
Assortment of 3, sold separately; "Customer will receive 1 item, styles will vary".
There is no trick, they aren't lying, it's not bait & switch.

They show you three toys, one will randomly be selected.

That said, BOTH of my girls LOOOOOOOOVED these toys. They didn't fall apart, tear, or come loose. My kids didn't break their teeth on them, because the toy was properly attached as the manufacturer intended, and they were properly supervised. The chiming sound is very soothing, and even after they moved on to larger car seats, I have kept these toys for their children. In the keepsake box they go! I purchased SEVERAL of these, YES at this VERY reasonable price, because they loved them so much.

I have no clue what these are, but my niece wanted them for her birthday and she absolutely loved them! So, if you know a kid who might want them, they'll love you for it!

I think 5 and up must be the play age. There is no way a 5 year old could put this thing together unless they were Hercules. The amount of force you have to use to push these things together us unreal. Some of the holes are partially closed up in the little joining spheres. I had to hollow a few out with my pocket knife to make them work. All complaints aside, the kids like it which is what is important.

It looks  my kids are wearing depends, or some sort of astronautical pull-up contraption.  HOwever, they do work well, so I can't knock them too much.  Luckily, the kids don't realize how funny they look in these things!

All of my kids loved these (as do I). We spent a long time playing tag with the cars. However I'm curious about the song that these cars play. It sounds like a Russian folk dance, not that I know anything about Russian folk dances, but it was an odd choice for this toy. Not a drawback, just curious as to the song selection.
