Disappointed with the quality
My 15yr built this model within a few hours. However, he was very disappointed with the mechanism. Despite, building it correctly, when he wound it, it started cracking and splintering the wood. Very disappointed.

Too fragile to construct
Only just tried to make this and disappointed that it’s far too fragile to construct even when handled delicately. The grain of the wood and thinness really is hard to work with. We were looking forward to making this so much.

Great holiday project
Bought as a holiday project for son and husband. Some parts are fiddley, but holds together nicely when complete, unfortunately balls can came out of some parts quite easily - nearly lost one. Looks as per image.

Too Delicate
Very flimsy - hence spare parts. Instructions (obviously for multi languages) very poor. Construction of middle section almost impossible.

POOR AND CONFUSING INSTRUCTIONS
I’ve built many of this type of model. First time trying this Company. I found the instructions were appalling. Unclear and confusing. Bits fitted as per the (poor) photos, but the next bits had nowhere to go! You can’t actually make the photos out. I sent it back and went for my usual Ugears or Rokr - which I’ve never had any issues with.

Der Aufbau hat Spaß gemacht, leider ist während dessen ein Teil gebrochen. Dieses haben wir aber nach Kontakt zum Hersteller problemlos Ersetzt bekommen. 👍🏼.

Took many hours to build this with my son, but he was truly happy all the time! Highly satisfying when it was done and to see the function! Recommend! 👍🏻

Da maneggiare con cura per evitare che si scheggino i pezzi staccandoli. Risultato finale apprezzabile.
