Hot Wheels Track Builder Rev 'n Launch Challenge, Multicolor, FLL02

Awesome booster for got wheels cars only issue I have if u have a child that his or her finger is more then 2 and a half inches and while this booster is cranked up and they stick there lil finger in they will get hurt no doubt, NO MY CHILD DIDNT GET HURT I TESTED IT ON MYSELF TO SEE WHAT THE DAMAGE COULD BE why??? Because u can easily get in there and touch it cranked or not so not a good idea whoever decided to put this out without some way of blocking it somehow for the kids other then that awesome wish I had one when I was younger they really get launched crazy far!!! Btw kids are always curious that is why I fully checked this out before I let mine use this and I watch them too while playing with all of are tracks set up.REALLY COOL

This thing is awesome. Even a small kid can rev it and launch cars at a crazy speed. Exponentially better than the other launchers which have you smack down to launch the car. It's also proven to be pretty durable, as my kids have shoved all sorts of stuff into it.

I bough this to go with new track that I got my sons for Christmas. They got the Hotwheels ID portal and I figured this would get the speeds up to a very insane level, and it does. That being said, please be careful with it. it has a saftey lid over the ejection shoot because the cars come out very fast and can get airborne. My oldest son (8) thought a car got stuck there and started to look in on the ejection side (several feet back), but it was not stuck, and it hit him square in the nose. It was a natural reaction to look, even though he had been warned. A little crying and and a bloody nose for a bit, but he was back to playing with it shortly after. This may also mark up your walls (chip them) if it were to launch cards that way at them. Please really stress to kids not to be on the other side of this when cars are going through, and to aim it into a closed loop track or at something you don't mind being hit by fast cars. Also, it has limitations for cars like the twin mill, a very popular short car, because it is not tall enough to hit the roller. Also the hot wheels ID VW bus is just a bit too tall for this, blows off the safety door and can jam it a bit, really close to scuffing the finish on the car also. Ovearll, 4 stars because of the safety concern and the car limitations, but still very neat.

Fair warning this thing launches cars at high velocity. And if setup just right will fling cars maybe 20-30 feet thru the air. Super fun. Easy to use.But just be ready for holes in your walls if your kids arent careful! Love it so far.

Purchased this as a part of my sons Christmas presents. He loves it. Its easy to use, hes 8 and easily assembled it himself. Its a great addition to any Hot wheel track collection and really propels the cars with alot of power. I like it alot! And more importantly so does he!

These are great. My 3 and 5 year old sons love them. My 1 year old even knows how to use it. Easy for the kids and fun. It really launches the cars, so ankles beware!

It says what it does. Just make sure you use hotwheels cars for proper use. The other brand toy cars have different dimensions

It's nice that this car launcher is not battery powered; I like that the kids have to use their own energy and I don't have to replace batteries repeatedly. It's also held up well to the typical kids abuse.However, there's a fatal flaw in the design - it tends to launch cars into the air, off the track. At this velocity, a Hot Wheels car could hurt a kid if it hit them in the face! The "going airborne" effect is worst with cars that have a spoiler on the back, but even our smoothest top cars will still go airborne when the launched is fully revved up.I think the problem is that the Rev 'n Launch booster wheel pushes on the top of the car. We don't have any issues with airborne cars when using boosters that push on the sides of the car, like the "Hot Wheels Track Builder Booster Pack Playset". But batteries come with their own set of annoyances, so I'm not sure if there is an ideal booster.
