I bought two of these to elevate my midi keyboard (Alesis VI49) on my desktop to have a wee bit more space for my desktop junk. It worked as expected! Even a single one might have been enough, but two seems more stable to me. The keyboard is almost a meter long.
Pros are,
it is very affordable for a laptopstand and has very sturdy, metal construction.
Its height is adjustable and it comes with foam padding on both surfaces.
Price is almost unbeatable!
Cons are,
the angle is fixed and adjusting something requires complete disassembly.
While using two of them to carry a thing, a keyboard in my case, two units are not identical to each other and one feet on each unit doesn't really undertake the weight as much as other two feet.
But since the actual usecase is different than what I use them for, I can't really complain...
Great work Thomann! Cheers,
