it fairly gets you down !!
anything Gravatrax is 5 star ,i have an extensive collection ,the only thing " wrong " is you have to reset the cups after every run ,but if you search online i believe you can over come that ,it's a great construction and the quality you would expect from Gravatrax !

So much fun!
This was a fab addition to the gravitrax starter kit. Each one connects to the next and it's just a really fun extra thing to add to the set!

not 100% reliable
interesting addition to a gravitrax set up and very impressive kinetics when it does work, however we have found it is very temperamental and often does not work as intended. we have had it work and fail on multiple attempts using the same set up, even the set up provided in the instruction book, soo good luck!

Fantastic product
Fantastic quality product. My 9 year old loves this and the transfer mechanism works every time and is great fun.

A bit fiddly
Bought for my 6 year old to add to his current set up. Even with my help it is a bit fiddly to incorporate this part into a track so that it actually works. Overall great toy but this addition is not worth the money

Brilliant creative add on for gravitrax set
Gravitas has been a firm favourite for my now 8 year old for over a year. Excellent creative toy with so many great add ons. This can’t be used on its own but a great little add on if you already have the starter pack
