“I was pretty disappointed in this. I wanted a small brush, but this was TOO small. I think the brush head size was good, but the handle is way too short to reach to the bottom of any of my drink bottles. I have no idea how well (if at all) the bristles work because I can't reach where I need to clean. :(”
“I have looked at a few brands - this is probably the only one that's reasonable in price and does the job just as well. I use it to clean my glass drinking water bottle, Soul Bottle, which has a larger neck. I don't think it will fit the glass bottle with a narrow neck.”
