Operated for 8 months
This hub, which I used to add 3 USB 2.0 peripherals, worked for about 8 months. Then, gradually, after a large transfer, the peripherals only appeared intermittently (electronic problem). The PC would often see the folders but not their contents.
In short, 10 months later, I can only use it half the time, half the ports.
Remember that a hub with 4 USB ports shares the power supply of a single USB 2.0 port in 4. Electronics are sensitive, and this can cause problems with voltage.
However, I've never had any data loss.
It's still a simple way of adding USB ports, but it has the durability of its low price.
