This is a very nice version of this effect. I like the movement up and down as it avoids the "static hanging" look of other versions. Took a star of due to noise factor. While not overly loud there is no way this could be performed without music cover. Even in a large room.

There is a reason the demo vid has a music track overlay. Nice effect but just know you will need to do this to music which this effect lends itself to a silent presentation anyway.

It's as advertised. Previous review is correct it is loud.
Must be done to music which only makes sense. The construction is ingenious but it looks cheap. For the money it should look much better and be silent. It works well though. The other issue is that the line will get wet which normally isn't a problem. But with this setup I'm wary of any harm to the mechanics from rust/stickiness. I expect to pay for the thought and inventiveness of our magic but for the cost of this, as a minimum, it should not be cheap looking plastic. I can live with the noise. The instructions are awful. I will continue to search for one of these that's much better quality as it's really a great effect.
