Very cool for 3 year olds

My son is into any kind of truck and he really likes this video.  Dave and Becky are kind-of annoying and the plot is hokey, but it works for toddlers.  You'll get your money out of this one. :)

We got this toy free from Fisher Price and the three year-old boy in our house loves it.  It stands almost as tall as he is. The gates are easy for him to switch up, and even the little gas pump sparks his imagination.  He's been using the 2 cars that came with it and other, similarly sized cars on it with no problem.

We've not had any problems with the cars getting stuck on the track, as others have mentioned, but when I put it together I made sure there were no gaps between pieces and the screws were done tight.  Did I mention there are a LOT of screws?? It is certainly a good thing for a toy like this to be sturdy, but assembly took 30-40 minutes because of all of the parts and the tiny screws. All in all, it was an easy job, however, with simple instructions.

I purchased this for my 3 year old nephew.  His eyes lit up when he opened it.  He was so excited
that he starting playing with it right away.  This was about 5 months ago and he still loves it
and plays with it often.

Trio blocks are awesome and fun.  I have a 3  year old and 7 year old and they love building with trio blocks.  With this gear set you can build things with movable parts.

These are really cool. My son LOVES robots, and these were given as a gift for this 3rd birthday, which was a robot party. Guests from 3 to 60+ were enjoying this toy. On the back of the box, it gives ideas of their stack-ability. Very cool gift.

I bought this toy for my son's 3 year old birthday. I ordered it late so it came after the party and all the presents. I have to say it was really easy to put together and my son's father was trying it out in the driveway the night before we gave it to him. It's alot of fun for kids, no matter how old. When ever my nephews come over (they are 6 & 9) it's the first thing they go for. They all want to try it. But it doesn't really hold my son's interest for too long. He gets on  it and rides it a for 10 or 15 minutes and then he may not look at it again for a few days. I think he would like it if it went faster but it's rider propelled so a 3 year old can't make it go as fast a an older child, still he does enjoy it when he rides it. Overall it is a fun toy and it's different than those big battery powered ride on's. It takes some thought for the child to figure out how to wiggle and steer at the same time. And it is affordable for what you get. The one thing they don't really mention is that it needs alot of flat pavement or indoor surface for it to be fun. It doesn't do well on bumpy surfaces.

MY SON LOVED IT very much.  It is a little cool toy.  My son (3 years old) dropped it on the follow and nothing happens.  And the audio and the sounds coming out are very clear.  nice

Excellent toy for kids under 3. It's very simple for them to manipulate. One simple motion "transforms" the toy.

I bought this for my 20 month old and i think I have more fun with it than he does! Its really cool. In this age group, it has to be used with supervision as there are small parts, but i will be a good toy for him to grow with. I would def buy this again.

I think I like playing with this more than my 3 year old. The sand is really cool! I bought it to help with my autistic son's sensory needs and he loves making the dinosaur molds. I also hide the other dinos in the sand so that he has to find them.  Would recommend.
