GO!!! Battery

Easy to put together. Cars are fast. Hours of fun. Takes some skill to keep cars from flying off track. Fun times. Great value too.

Great nephew loved it! Played for hours.

It works and it's fun, just like the old car sets, it works the exact same way, same technology, keep in mind, its not a defect, part of the game is to not press down on the controller too hard or I'll go too fast and fly off thr track,

Was bought for a gift and it was a hit! Super easy to assemble and cars work as intended. Would buy again.

Great product

kids love it batters last longer than expected

Product didn’t work adequately. Only one track was working the parts the go kart the was falling apart not a good product.

mt grandson loved this

海外からの発送なので心配していましたが梱包もしっかりしていて孫もよろこんでいました。

Great little racetrack, my Grandson and I have had a great time with it.

La pista está muy bonita de buena calidad los materiales, fácil de usar y a mi hijo le encantó

Love this set so much, easy to assemble (a bit of effort to connect all the tracks, but understandable, these are electric components). Quality is great, the little mario cars are just so fantastic and cute, but mostly when they zip around the track so fast, it's just so cool! Easy to operate with single button to press to vary the speed, so is really really great fun for me and my kids, and we are fighting to play it. The set looks of real solid build, the track itself, the cards, the controllers, so it seems to me like will last a long time. However, the wearable conductor at bottom of car, not too sure how long that will last, but understood it is meant to wear out. Then you can reconfigure the track anyhow you want which is fantastic! BUT a few things which is a bit of downside: 1) The car bits at the back broke off after a while (one side of the jets) coz after many times going off track, this is the weak point. Can re-attach loosely, but perhaps should have been moulded in place? I will probably super glue it back. 2) The set I have does not come with power transformer which is a shame, because the batteries are the hard to find giant D size batteries, and they will last a good day of 2 of heavy usage, but ultimately you should have the power transformer. It doesn't come with it, and it's not that easy to procure I find, so it kinda stops the momentum of the fun after a while. Overall I love this, everyone will love it, even those who don't play with toys!

Mario’s car does not work; it’s missing some of the aluminum at the bottom, and Luigi’s car goes off track. My kids were very disappointed!
