It does the job but the handle is quite long. I bought these to wash my childrens water bottles and it would be easier to use if it had a shorter handle. If you need them for bigger sized bottles like litre bottles then it would be more suitable. Also the handle bends when you are trying to apply a bit of pressure to scrub the inside of the bottles.
Just what I needed to clean a tall drinks bottle. Decent quality for the price. End of brush to end of handle is 39cm. Brush section is 10cm or 14cm if you include the section of wire holding the brush. Diameter of brush is 5cm. Perfect for my needs so would recommend.
