I thought I could add this tray under my studio desk for my Native Kontrol S61.
First, items had slight damages out of the package. Protections within the package are very minimal but the pieces are quiet heavy.
Then, there's no assembly instructions at all. I contacted the support and they redirected me to the constructor website with all the instruction videos. But this tray is an option and among all the videos, there's no assembly support for this product.
Also, product description is not accurate. The tray is curved on one side.
Im the guy who can build an entire kitchen but I couldnt succeed mounting those rails. The constructor website says excellent craftmanship but even Ikea sliding rails are way better, smarter and easier to mount.
Today Im offered to send it back for replacement, which is fair, but cant get refund. I would totally not recommend this product for your keyboard under your desk, unless maybe you get the whole Studio Desk Proline from the brand. I will go for a cheaper standard keyboard stand.
289€ wasted.
