First of all, I'd like to address others' concerns about whether it fits all devices properly and screws. I personally do not use the screws that come with my rack devices to be honest. I purchased the Raxxess Rack Screws (also available here on Sweetwater) for like $5 and use those (to me they look/work better anyway.) Never had any problems, and all my gear has always fit perfectly.
Now to the baffling thing about this series... I absolutely LOVE how it looks... it's sturdy as hell... and it has never given me any problems or quality concerns. Not only do I use it to hold all my (expensive) gear, I also put my computer on top of it (27'' $2,500 iMac) so it should be a given that I trust my stuff on/in it. So why baffling? Because it was so damned inexpensive. Granted, it's not extremely high quality wood or anything. But it looks great (mine had 20ru) and cost only 100 bucks.
Anyone giving this less than 5 stars doesn't quite grasp what "Bang for buck" means. It's happily sitting in the center of my home studio.
