Will buy more if I can find

These were exactly what I was looking for. I have both a 40oz water bottle and a 16oz Zojirushi bottle that I use quite frequently, and I was having a really hard time washing them thoroughly with a sponge alone. I was ecstatic that these brushes were long enough to comfortably clean the 40oz bottle, PLUS the heads fit in the opening of the Zojirushi bottle which are under 2" wide. I didn't realize how much residue I was leaving behind in my bottles using a sponge until I cleaned them with this brush and they looked brand new inside! Really glad I made this purchase.

These are long enough to reach the bottom of 1 litre drink bottles with ease. Bristles are sturdy enough that they clean the bottles properly. Great for cleaning tea pot as well.

Es lo que esperaba, duran mucho y son robustas

I bought a set of three brushes but was sceptical about the positive reviews. However, I am very pleased as they are sturdy and robust. I bought them initially to clean my kids water bottles. They have a longer than usual handle which allows me to reach right to the bottom of the bottle and it has sturdy bristles which clean the bottle's base and sides thoroughly. The handle is comfortable to hold and does not bend or snap when a light pressure is applied. I like the fact there are bristles at the top of the brush to clean properly leaving the bottom of the bottle clean. I have also used them for wine glasses and my coffee mugs as it does such a great job of reaching difficult to get delicate areas on glass and also the stubborn coffee stains off mugs. I have bought so many different types of brushes over the years and these are definitely the best so far! A pleasant surprise that they do the job without rusting or snapping or the bristles breaking. These brushes bristles still look great after several weeks of daily usage!
