Sponge Vacuum Cup Cleaning Brush For Glass Bottle Thermos Mug Cleaning Tool

It’s smaller than it looks like in the picture.

cheap, cheap, cheap piece of junk. Much shorter handle than shown in picture. I do not see this item lasting more than 1-2 uses.

Meah... It kind of works, but it is too short for a water bottle (20oz) and I don't see how it will last more than a few days, it's kind of cheap.

Just right configuration to do the job!
