Review on 🧽 Long Handle Silicone Bottle Cleaning Brush - 12.5" Water Bottle Cleaner for Baby Bottles, Hydro Flask, Sports Bottle, Vase, Glassware - Perfect for Narrow Bottle Openings - One Pack by Mark Loebis

Although strong enough, the size was much smaller than expected. Yes I have an AA battery next to it and it is visible in the usual short glass. Unlike large-headed brushes, you don't have the effect of the brush applying more than one spot on one side at a time, and there's no cross-resistance to aid in cleaning. This might be great for very small bottles, but would be impractical even for thin baby bottles. I was looking forward to easy cleaning and a hygienic glass brush, but it's not big enough to get in the way while working.
