I have my 27' iMac on what could be the smallest desk dimension available at IKEA. My iMac accessories such as ext. HDD and ODD were just scattered on my desk until I got this neat gizmo - with my iMac base set on the highest height setting on HiRise, I now have decent room to put both my peripherals + other goodies as well.
I would have to point out though it felt quite overpriced for what it offers.
The product does exactly what it is meant for although not much more. The craftsmanship is excellent, sturdy, and stylish. When using the monitor looks at bit more heavy than I would want. It takes away some from the sleek-ness of the monitor, however, a necessary trade off to elevate to a comfortable height.
