I have numerous of water bottles ranging in sizes. Hydro Flask, Swells, etc. The mouth opening for each one is different and the water capacity as well. I needed a bottle brush that would fit narrow mouths. This water bottle brush was perfect for that. I was able to squeeze the main brush in for a good scrub and use the tinier brushes for the lid. The handle was comfortable to hold and the bristles were not that hard that it would scratch my water bottles. The brushes are attached together with a ring so the set will always stay together. The thinnest brush can even clean out the lids with straws. I was surprised how I was able to squeeze that one in.
Overall this is a must have for water bottle owners. It is easy to use and a great way to keep your water bottles clean. It does not feel cheap in any way and should last a long time.
