“Love the brush. the secrete is to squeeze it tight so that the brush fits down the narrow mouth of the bottles. the long handle makes it really easy to get the bottom.”
“I tried it on my 34oz glass bottle, it was tough getting it into the bottle the brush is wide and not quite long enough. I bet it would be better with a 20oz bottle.”
“The bottle brush is supposedly designed for Waterdrop specific bottles. However, I had a very hard time getting the brush into my 34 oz bottle. I felt like I was breaking the brush as I forced it through the small opening. The brush is also not long enough to reach the bottom of the bottle, making it difficult to clean the bottom. Would not recommend purchasing this. You will be better off buying something cheaper that will actually work.”
