The design is very clever and I enjoy making this sort of kit but like all these smaller and cheaper models there are one or two problems. Firstly the plywood is very thin and sometimes damage occurs when attempting to get the individual parts separated from the the board or simply when assembling the kit. Secondly the printed instructions, mostly consisting of black and white line drawings, are not always very clear. However this actually makes the 'project' even more challenging. You do need to have dexterous fingers and endless patience but where's the joy in being able to make the model in 5 minutes??
