Review on ๐ ๏ธ ROKR Perpetual Mechanical Engineering Supplies: Unbeatable Efficiency for Engineers by Bernard Larjin
Neat Puzzle Calendar
This calendar model is pretty neat. Gathering was easy and straightforward. It took about an hour to assemble (I have experience with models from this brand). The movement is pretty smooth. At the turn of the year it hangs a little, even grinding and waxing when assembling, but nothing to complain about. After assembling it and making sure it worked, I used some glue left over from the previous model to add some stiffness to the locks on the sides and bottom, but that was optional, not necessary. It's a pretty piece on our bookshelf.
- Excellent Overall
- Almost Never
