I had read quite a few reviews about this before I bought this. One of the reviews did mention that feels a bit weak when you try to scrub the bottle. I agree with that review, but it's still good. I figure out, instead of going in a round motion, I just have to scrub it in a up-and-down motion, that gives it more force when scrubbing. But I won't use this to clean wine glass, as that metal end in the brush keeps clinging with the base of my delicate wine glass, I kind of worry that either I will scratch the bottom or it will break the glass.
