Metal Earth is a range of laser cut 3D models. They have the rights to various licensed models from series such as Star Wars and Halo. I picked up the R2D2 model and decided to give it a try.  

So it took me a very long time to assemble the model, and it was not easy. The model has various tiny pieces (I spent a lot of time crawling around the floor looking for dropped pieces no bigger than a large grain of sand) and I found normal needle nose pliers too big for most of the assembly.

Assembly of the model was extremely frustrating and I believe for anyone with large hands building these models would be nearly impossible.

The model came out looking ok, but not close to the one on the packaging and I can only assume they got a neurosurgeon with the hand size of a small child to assemble the one displayed. 

These models are a novel idea, and I believe that if you build numerous models and invest in specialised tools, eventually you can become better at building them. But even considering this, I cannot recommend these models to anyone except the most dedicated and experienced model builders. They are simply too frustrating and finicky to assemble. Simply put, it wasn’t fun.
