Review on π© The Ultimate Rotating Mechanical Constructor for Engineering Enthusiasts: Perfect for Adults and Teenagers by Michael Mayes
does not run smoothly parts were missing
the balls keep getting stuck in the big wheel so that everything no longer works - but at the relatively low price I think that is appropriate and fair. The second set had two "C" sheets of plywood for parts but no "D" sheets of plywood, so parts were missing and I couldn't assemble the model.
- good
- almost everything ok
