Wooden Trebuchet Kit

This is a horrible kit. Although I didn't buy this from Amazon, it's horrible enough for me to want to make sure NO ONE buys this kit by accident thinking it's a good kit. The craftsmanship is horrible. Splinters everywhere. Holes aren't aligned. Dowels don't fit pre-drilled holes. Pre-drilled holes aren't centered so wood splits easily. Instructions aren't clear, drawings look like a 5 year old made them. If this thing cost like $9, maybe it would be ok. But $30? STAY AWAY. We bought 10 of these for a group project, and all 10 were horrible.
