I bought this a couple of years ago to house my Steinberug UR824. It's perfect for it.
My UR824 soundcard sits mostly in the studio. I have a smaller one for on location work. But sometimes, mostly for multichannel work, I need to have my UR824 with me. The UR824 fits narrowly into this case, but just to be sure I put some aluminum plates between the handles of the soundcard and the railing with the screws, to gain a few mm, and then the soundcard fits perfectly. What I really like about this case is that it is very light. I mostly go by foot or public transport to my jobs, and then this easy to carry, while still providing enough protection to the soundcard. Once I'm on location, I'm also very quickly setup, which is always appreaciated. It might not be sturdy enough for daily life on the road, but for occasional travel, it's perfect. Over the years I took it out quite a bit and it took a few bumps along the road but it's still in perfect condition and it has saved the soundcard from some mishaps. On location it usually also doubles as a laptop stand.
