Review on ๐Ÿ› ๏ธ ROKR Perpetual Mechanical Engineering Supplies: Unbeatable Efficiency for Engineers by Robert Goodlow

Revainrating 4 out of 5

Imaginative, fun and stimulating desk toy

The assembly instructions are simple, although the wooden connecting pins can easily be lost. It is incomprehensible to the mind to hold a calendar for 20 years in your hands! The gearing system is incredibly intuitive and I often look for reasons to compare it to future dates (unfortunately only 2018-2040). It even accounts for leap years correctly! This makes a great desk toy or conversation piece and is very well detailed. I hope they do a bigger one to cover more time or do a metal version but it's awesome!

Pros
  • It's OK!
Cons
  • Nothing
