We really like the drinkware brush, it is just the right size, and the curve at the end is great for all kinds of glasses and small vases.
It's a great brush and would give it a 5 star rating but the end of the brush doesn't fit in the bottle I have (too big of brush end)
10/10 will be purchase more products from Bamboo Switch in the future.
I had to force the brush into the opening of my Nalgene water bottle but once in it worked great
