For a unit with so many pre-drilled holes, I found it pretty funny that none of them matched my unit (a half-rack-width Golden Age Comp-3A). Cant really hold that against them though, and it's nothing that a drill and 6 terrible attempts at drilling 2 holes in the right place won't fix!
Sagged a little in the middle, but nowhere near as badly as the Flyht shelf I bought. The sagging can also be significantly improved by propping up the middle of the shelf while mounting it
As with the Flyht shelf I bought, this one arrived drowning in polystyrene packaging. It's 2024 and this is a robust chunk of metal, not a priceless vase. There are plenty of less environmentally horrible things than polystyrene that could have done the job here.
