Only two pieces to put together :) I had to find a youtube video to show me how. I'm a strong woman, but that lid just didn't snap on the can the way I thought it should. Once I saw someone do it on video, I had to laugh, it was really simple. Simplehuman. The can is narrow and fits nicely next to my sink and that counter, and my dogs are ever so disappointed that they can't get into the delicious contents anymore. Boo for them, yay for me. I'm happy!
