Used Evenflo Simple Step Does Anyone Know Any Good Bottle Brushes?

Does anyone know any good bottle brushes? - used evenflo simple step

I know it's probably a simple question ... but I went through almost all babies R Us brushes I tried Evenflo, Nuby, the early years ... All end the same way. The smaller sponge on the ground there in about a week. It always seems too thick to fit into the normal size bottles. "I wash the bottle one million times to my twins and I use a cup of juice to wash my child all day. All the ideas for a good bottle brush? Who has used, and swear?" I am with my new brush every weeks tired.
