I bought these a few weeks ago after a power cut in my area had me worried about surge protection. The design is pretty cool. So far all good. The only thing to note is that this will either need to dangle from a desk etc when all 5 power outlets are occupied, or if it is sitting on a flat surface, one of the power leads inserted into this will need a flat back so that this device and everything plugged into it can rest on the bottom lead plugged in.
