Currently using this with a Yamaha Montage 7 as my main keyboard, and have just added the 2-tier holders from the bundle purchase so far. It’s quite stable and build quality is top notch.
I bought it to replace a Jaspers 6D-150B whilst swapping out most of my equipment into a more manageable setup. This stand is has a very compact appearance also when loaded with gear and extras. However, coming from the Jaspers system, I find flexibility with the Omega somewhat limited, despite a descent range of optional holders and accessories.
Some of the accessories will add to the overall size in unwanted directions as well. Mixing-and-matching various parts for a custom fit is rather limited, unlike the Jaspers. Also, the bottom keyboard must be removed in order to change any additional holders.
The main parts have fixed steps for heights, widths and angles, which makes symmetrical adjustments a breeze compared to freely adjustable designs. Although being limited to 3 tiers, it would have been nice to have a wider and denser grid of mount points to fit 2-3 mid-sized devices on the second tier. This system has a few such missed potentials that would otherwise have made it perfect.
It makes a very nice solution nonetheless, with some possibilities for customization. If you're looking for a slim and bounce resistant stand to hold 1-3 regular keyboards, this is it.
