Review: Great Kit, lots of fun! - My nephew LOVES these kits. He likes that once it's out together, he can play with it....it's not just a model. The item shipped promptly and seller provides exceptional service. I would recommend this kit and this seller.
Review: Fun and Educational Toy/Model - This was a fun toy/model to build. I spent about 3-4 hours just taking my time enjoying the process and learning how this machine works. Everything you need to build it is included (glue, rubber bands), it even comes with a clay block that you use to create ammunition. I would recommend having some clamps available to hold pieces together while the glue dries. The sling takes some care in setting up correctly to actually throw the ammo in an arc. I used some crayon to wax certain areas of the wood that come in contact with the string, this helped provide a smoother surface than the raw wood for the string to glide across. I then used the rest of a crayon to put a thin coat of wax on all string areas to protect the string a bit. Overall, it's a fun toy that I I use to launch clay projectiles across the room at co-workers!
