Bottle Cleaning Brush

Works well for bottles and cups. Not very long, so can be challenging find for really tall bottles. I have a different prism for that. But I like using this one for the rest of my stuff as my go-to. Some bristles fall off but hasn't been excessive for us.

Good design, poor construction. Bristles started to fall out first time I used this. I used pliers to twist the metal tighter on the end, but that didn't seem to help. This is a great idea, and the shape seems effective, it's just unfortunate that the bristles are falling out so quickly.

Too short

The handle is too short, it does not reach the bottom of my thermos But the bristles work well on what they can reach
