“Nice sturdy brush, a bit of a push to get it in the bottle, doesn’t fully reach the inner curve at the top of the bottle, and on the 34 oz it is hard to hold the handle and brush.”
“I am so happy this bottle brush was an option! It is an absolute must have for ease of cleaning out your waterdrop bottles, I am even able to use it on all my other hydroflasks we already own! It having a wire under the brushes allowed me to put a slight bend in it to reach all the corners inside my glass waterdrop bottle!!!”
