My son has played with this on concrete for a couple of months and the cover is already coming off.  Not for concrete!

This construction toy is providing a lot of fun for a family of three little boys under the age of 7.  The durability is its biggest trait from a value point of view.  It's been to the beach, the backyard sandbox, and pushed all over the sidewalks and yard and still looks new.  Looking forward to bring dinosaurs out of extinction and adding more of these ferociously fun construction toys for these boys.

Used this on concrete to teach some hockey to a 3 year old.

It's heavy.  It moves well for handling.  Balls are still rolling fine after use in a racket ball court that had lots of old leaf piles and debris.  From the still-works-after-it-gets-dirty perspective, it's durable.  Husband tried hitting it really hard a few times.  It's structurally sound, but very heavy and not so good for shots.  He says heavier than a real hockey puck.

My 9 year old son wanted this toy sooo bad for Christmas. Well, he got it, and was probably the happiest kid on the block. He took it outside to drive it in the snow, (because it says it will go in the snow) and it kept getting stuck. However, the snow was the hard icy kind not the soft fluffy kind. Anyway, I think he has played with it a total of 3 times and it has just been sitting in our garage collecting dust. For some reason he just doesn't find it as cool as he thought it was going to be.

Yes, on the kitchen floor it just spins and spins and won't move forward, like the other reviews mention. However, on cement it works like a charm. My 3 year old truck loving boy adores it.

Eta: My husband just wrapped scotch tape around the back tires (sticky side outward) so it sticks to the floor better, and now it works just fine on the tile floor. Great for a 3 year old, but I wouldn't suggest it for an older child.

I bought this for my 3 year-old son. He immediately climbed on and began spinning around on it. We have hardwood floors and he's been using it since we got it a week ago. It hasn't left any marks. We'll keep it inside so the bottom stays slick. The plastic is really tough. We'll probably order more so friends can play at the same time. Husband too.

My son loves this and it has held up well, even after being used as a frisbee all summer and sometimes ending up in our dogs mouth.

As soon as my car- and truck-loving he saw me take this out of the box, he was at my feet waiting. Luckily he was somewhat patient, as it's secured to the cardboard backing with about 340 twist ties (okay, maybe 10). Each attachment has a specific place to go, but all the pieces can also fit in every other spot for creative fun! I think he played with it for an hour straight. It would be nice if there was a volume button on it, but it wasn't that annoying (maybe because my son likes just playing with it as a truck and wasn't terribly into making it make noise). Like most Tonka toys, this thing is sturdy. It's been in use about a week or so now, so it's been dropped and played with on the cement and it still look good and works. There's not much educational value to it (other than being able to be creative in putting the pieces on in different places), but it's such a fun toy and my son loved it so much that I'm rating it five stars. I'll come back to update once it's been in use a bit longer.

It's a decent price, it lights up and makes sounds.  It runs on its own and turns around when it bumps into things.  My son watches this run all over the house for a very long time and just thinks it's the greatest thing.  The plastic quality of the toy is not the most durable, however my son is 3 and not the most gentle little boy, and it's still holding up strong against him, so I can't complain.  He is able to turn it on and off himself.  The noises aren't too loud and don't bother me when he plays with it, which is definitely a plus.  It does come with a cap over the turning wheels that I had to take off, but I didn't realize at first and I thought the toy was broken.  For the price, it's definitely a decent toy and it had provided my son with hours of entertainment so far and still going strong.  The ladder does go up, and makes a clicking sound while it does.  I did receive this toy at a discount in exchange for my honest opinion.

Bought this when my son was about 1 year old and he is yet to play with it for more than a minute at a time.  It is durable and the noise level is low. My son plays with all of his other trucks, bigger and smaller, but I cannot get him to enjoy this one.

This looked like the most fun a kid could have...to me. I sucked up the price because I imagined my son playing on it for hours. My two and a half year old rides it occasionally but enjoys it much more when he can rope an adult into pushing him "really fast".  Now most of the time he uses it as a ramp for his cars and trains. Which I guess is okay too. My 11 month old boy enjoys crawling up and down on the track but occasionally there are fights as both of them want to use the track at the same time and can be dangerous if the little one gets in the way of the car.

One thing about this expensive toy that has not lost it's charm after 3 months is the big box it comes in.  We cut out windows and a sky light to be Nate's "house" and his hide away from baby brother, it affords him a few minutes of peace anyway.

My daughter received this toy to review for free. She was not interested in it at all when we first took it out of the package. As it has sat in our playroom, she has started to play with it more and more. I don't know what the original hesitation was about, although I believe it probably had something to do with the fact that the only other construction vehicle that she has is battery operated and moves on its own with the push of a button. We haven't had a chance to get this outside to test for its durability but it looks like it will hold up well out in the elements. I am sure she will enjoy making tracks in the dirt with it and scooping up dirt and mulch with the t-rex head.

This is a lot of fun. My son (5) loves to play with this to chomp on other stuffs, dinosaurs, cars, and people. I like it too. It is made for adult hand so for little ones, it's a little difficult to control the jaw. My son use two hands on this. It's soft, and no teeth are missing when arrived (other reviewers mentioned about broken tooth).

UPDATE: After two months of owning this, one of the tooth is  broken/torn.  It looks like if you chomp it too much /too hard the teeth get smashed by whatever you are chomping on. Also, the excitement died down after a few weeks and it has mostly been just sitting on the toy bin.

It was not smooth rolling on concrete.  It started cracking a little.  Not intended for rough surfaces.  Plus it is a very hard material.

My son has had this thing since he was born and he loves it to this day. It is beat up and been thrown all over the place, but it's still going!
