This is a great kit As with all metal earth kits it pays to take your time making sure that you follow the instructions and handle the small parts carefully when bending and shaping them so they don't break. I use the following tools to help: Small snippets to remove parts from the sheet. Long nose pliers to bend pieces into shape and bend or twist tabs. Various small tweezers to bend and shape parts and get to hard to reach tabs. Various screw drivers/tools with different diameters to bend cylindrical parts. Took me about 6 hours to build and now sits along side my R2-D2 metal earth model.
