YES - beware - it may also be identified on the case as "7-Hub" or similar. When I disassembled the hub, I saw why it didn't work - bridged tracks and solder "sputter" all over the board. On disassembling the power adaptor, I was absolutely horrified to see that there was no insulation covering the power pins inside the device as there should be. Again ,soldering was dire. I immediately back-claimed on the (Amazon-listed) supplier and he has been removed from Amazon. A little detective work, and I traced the supplier to Birmingham, UK, despite their use of PO boxes. Trading standards have visited the premises and taken away a considerable amount of counterfeit and dangerous goods.
Too cheap to be true - you bet! As a qualified electrical and electronics engineer, I can unequivocally say that these devices are dangerous to life.
