Original-Equipment. The world’s foremost automotive brands put their confidence in Bilstein quality. Why? Because brand develops and series-produce suspension components in collaboration with Bilstein partners from the automotive industry. By placing your trust in Bilstein experience too, you'll be opting for the Bilstein driving experience when you exchange your suspension components.

Gas Pressure Technology. Over time, the mono-tube gas pressure technology developed by Bilstein has established itself as a standard in automotive construction. This technology involves keeping the oil in the absorber under pressure, which prevents it from foaming when temperatures and loads are increasing. As a result, full damping power is retained even when the system is placed under extreme stress, a feature that can be observed in the self-lowering piston.

Mono-tube Upside-Down Technology. The original and best: The original mono-tube gas pressure shock absorbers bore the Bilstein name, and we're still responsible for producing the best there is. Bilstein's mono-tube technology is the number-one choice in motorsports and series-production sports cars: no other type gives engineers the same freedom to choose the perfect installation location or position (e.g. Upside-Down technology).

Twin-tube Technology. The proven technology of a twin-tube absorber is applied in the vast majority of all vehicles. Bilstein‘s twin-tube absorbers, featuring "original equipment manufacturer” quality that has undergone rigorous testing, offer a marked improvement in driving characteristics with universal spare parts replaced in a timely and efficient manner.

Good device! I was able to mount it between 2 desks that are head to head, and we’re able to share the plugs very well. Plenty of space to mount on my 2” thick desk.

Great value and capacity for the real estate ratio is perfect.
It certainly takes up less real estate on my desk with a very high port capacity. It's solid and I like the fact that it can attached to a thicker surface. It was very easy to install and the plugs give good options as there's always some cord that can't be plugged in. The USBs are a bonus as I already have ports on a different device. But, I'm sure I'll end up using these USB ports eventually. The value is really good for the capacity you get. Having the strip further in to use the back plugs easier makes a lot of sense. Could be an issue for some who don't have table real estate as it does push the strip in a bit.
