Review on UGEARS Archballista Tower Mechanical Brainteaser Birthday by Iration Mccall
Mechanically interesting, but very difficult to build. Not suitable for assembly by children.
This is my fourth UGears model and by far the most complex and technically interesting. Like others I had to make a few modifications to make it work well and make it HEAVY to build. Please note these models are really not suitable for children to assemble as you will need STRONG pressure to push the pieces together. Pro tip: CAREFULLY use a pipe wrench to gently squeeze the strongest parts. At least there are no errors in the instructions. I spent about 6 hours creating this but unfortunately my 9 year old lost interest after about 10 minutes. :-/
