Query: This has barely been usable

The area on the bottom is a pain in the neck, since you have to hold the top to get the zipper to zip. The containers that came with it leaked, and should not be used. I wish I had gone for a simpler kit instead. The material is already starting to show some wear, and I don't think it will hold up to heavy use. When it goes, I will get a plain leather kit.
