Review on 🧼 16-inch Bottle Brush Cleaner for Water Bottles - Extended Handle Brush for Cleaning Thermos, Hydro Flask, Contigo, S’Well, Simple Modern, Narrow Neck Sport Bottles, Kombucha, Beer Bottles, and Jugs - Set of 2 by Tracy Smith

I bought these brushes about 3 months ago. I use the straw brush frequently, about 3-4 times a week, and the bottle brush less frequently, maybe once a week when sanitizing my water bottles. You can see in the photos above that the bristles are now falling out. I have a second brush that I've been using for over a year and I've never noticed its bristles falling out. I do not recommend this product just because you need to replace it.
