A PLACE FOR YOUR HEADSET
Size: Small Storage Area, Size: Small Storage Area
This holder is fantastic, if you have the steel series headset and extra batteries it's perfect you'll love it, but would like to see a white version as well.

Not quite right
Size: Small Storage Area
this is "as advertised" but a simple extra ridge of plastic would have made it perfect. the issue people are having with the arctis pro, the thing that makes you want a stand for it, is the base station is a little too light, you can push it when you go to use the knob's integrated button. Issue here is the fit of the base is loose enough, you can still push the base out of the back. So it looks nice, and gives you a place to put the headphones and some other desk clutter, but it doesn't REALLY solve the problem.

3D Printed (Not Mentioned) and Base is Way Too Loose
Size: Small Storage Area, Size: Small Storage Area
I bought this to clean up my desk setup for my SteelSeries Nova Pro Wireless, and while it looks decent from a distance, there are two major issues that weren't clear from the product page. First, this is a 3D-printed product. Nowhere in the Amazon description or photos does it state that this is 3D printed. You can clearly see the layer lines and "stair-stepping" on the curves. While I don't mind 3D printing in general, for this price point, I expected a standard injection-molded plastic finish. The product page feels a bit misleading by omitting this detail. Second, the fit is very poor. The "integrated dock" for the GameDAC station doesn't actually lock into place. There is no snap or friction fit; it sits so loosely that you can slide the DAC out of the front or back with the single push of a finger. This makes it feel unstable, especially when you are trying to use the volume dial or swap out batteries. Bottom Line: It’s a nice idea and fits the aesthetic of the headset, but the execution feels like a prototype rather than a finished consumer product. If you're looking for a secure "lock-in" feel for your expensive base station, this isn't it.

it’s really small in depth
Very difficult to open and watch your finger so you don’t pinch them. Great idea. But too short and length or width so I have to send it back.

Compact and looks nice
I got this drying rack to install on the wall over my tub. It's great because I can just pull it out to air-dry my delicates. I can also open it up and use it as a light table to hold my phone and book if I'm taking a bath - dual-purpose! And the hooks are great to hang bath accessories. The best part is that it tucks in to blend with the bathroom wall. It's a very high-end drying rack.
