Query: Not easy to use; waste of money

While I like the fact that this has a lid, it is not the easiest thing to use. It's awkward to stick my dog's paw in, and the plastic flaps make it difficult to get it out. I also don't think it does much to actually clean my dog's paws. I am better off using a simple plastic bowl that I fill with water.
