Excellent brush. I use it for all sorts of things. It's particularly good for scrubbing bathroom tiles, and after a while I retire it to more mucky outside jobs and get a fresh one for indoors. Very sturdy, and the bristles stay in good condition for a long time. Highly recommended.
I imagined this brush to be almost twice its size, it is approx 15cm long (just under 6 inches). Having said that, it is sturdy and the soft grip is helpful but, because of its size I found it does not sit too comfortably in your hand. Despite this, I still find it to be a very useful brush at a very reasonable price.
