Mostly unusable
I have no idea how wide the neck of a bottle has to be, but all the bottles I tried to use this on were too narrow.<br />The handle is too flimsy to get any kind of cleaning done (you can get more out just swirling the soapy water in the bottle). I don't think I've used this brush more than ten times, and the wire handle broke. It is now in the garbage.
