All user reviews for the Hercules Stands KS210B

I was considering buying the conventional system with extensions tubes set foot in X, then I discovered this product.

Damage that the adjustment of the height of the extension is done by "holes" instead of clamping, for the extension arms are rickety.
Damage as the inclination is not adjustable.
In that the extensions are occasions bottom adds rigidity, for both the first and second keyboard.

However, a major flaw that any handyman can correct: in a low position, not possible to adjust the second keyboard low enough to make it playable.
It is necessary to shorten the two tubes extending 5 cm.

Then, but it's related to system setting positions "hole" there is too much difference between the two positions lower, the lower is a little too low, and the one immediately above is a bit high; but it is more difficult to correct, and also related to the thickness of your keyboard.

It's still a good product, but too expensive!
