Review: Great Metal Puzzle. - You will need to buy some special tools. This was a 7 out of 10 on difficult level. Overall it was alot of fun. This was my first metal puzzle and I made a few mistake but overall I think it turned out good for my likings.
Review: Interesting challenge, patience required - I have done a variety of block and wood based building kits, but this 3D metal model was a new challenge for me. I did order a set of tools for metal models in preparation for putting it together (the brand sells one directly, but I got a different option with more tools). The kit was definitely smaller than I expected. It also requires much more intricate detail work than any kit I've done before. You have to clip out tiny pieces of metal from the sheets, shape them individually with bends and folds, and carefully piece them together (usually by inserting tabs into small slots and folding or twisting the tabs to secure them). Many of the pieces are very small, and I almost wish I had a magnet on hand to find them on the floor in case of drops. You will definitely want to work in a brightly lit area for maximum visibility. You will absolutely need, at the least, small needle nose pliers, a metal clipper, and very steady hands. I had initially hoped to knock this out in a weekend, but honestly, it's such a challenge and requires so much focus that trying to do more than 1 section of the instructions in a session can start to get frustrating (there are 20 sections total). It's not really like Legos where you can reposition pieces if you make a mistake; if you don't bend the metal just right, it won't fit into the tiny slots, and you're out of luck. And once you attach pieces, it's not like you can unfold the metal and take it apart. I imagine something requiring that level of precision would be rewarding to some, but I quickly realized I'm better off pacing myself. Maybe because this is my first experience with this type of kit, but I found the instructions to be less than intuitive. I was constantly having to double check the color and symbol keys for the different types of metal folds, which parts of drawings represented the front or marked sides of the metal, etc. I found that it was at times a challenge to identify directionality of the steps indicated, and also that following shaping directions (ex. rolling a piece of metal into a ring shape) didn't necessarily guarantee correct sizing (so that the tabs fit in the right slots). It is highly detailed, and I imagine the final product will look pretty cool...it's just going to take longer than anticipated to get to it given my lack of previous metal model experience. The "for adults" is right, though maybe a very patient, very careful older (16+) teenager with model building experience could enjoy it too.
