This is not the cheapest powered USB 2 hub, but it is a very well made one, with a substantial 3 Amp power supply that delivers the goods even with heavy loads - a couple of USB-powered Hard Drives, for example, and the more-than-the-USB-hub-spec Raspberry Pi. Provided cables and connectors look to be of good quality. One can use this hub to connect USB things to the Pi as well as providing adequate power, we need 2 ports for keyboard and mouse, often a third port for HDD, and the others feed a slew of other miscellaneous items such as card readers and the like. We had it driving both the Pi, with its keyboard and mouse plus two USB-powered HDDs as a test, which it passed. Unlike some other hubs, the power supply has the proper UK mains plug on it. USB performance seems fine, there are 5 ports on the sides, and 2 more on the top underneath a sliding panel. Strongly recommended.
