Its polished aluminum coating is the most beautiful effect, and the hub remains cool thanks to the presence of this metal. I imagine a small part of the heat from the USB 3, which tend to heat is absorbed by aluminum; it's a good thing.
Second positive point: the ports are spaced 1 cm, which allows to plug any device, even a little thick. On the other hubs, there is usually 5 or 7 mm, which can be annoying.
The underside of the product is covered with a very soft foam plate which prevents scratching that on which it is placed. I would have preferred it to be of non-slip rubber, but it's nice to have thought about the surface of our offices and computers!
The shape of the hub makes it possible to drive the device with one hand without seeing the escape under the pressure exerted.
No complaints about the transfer speed: it is equivalent to that obtained without the hub.
I will end on a fault that I find quite annoying: the ports and we must cling force a little to insert and remove the devices. I tested with external hard drives and USB keys of different brands, and the conclusion is always the same: it catches much as my other hubs Too bad!
