I have very bad experience with Sipolar 10-port. I have had 3 units go back in a matter of months. The power plug tip and the receptacle goes bad. This is a common issue, so this is a manufacturing defect that Sipolar will not address. They just tell you they will give $10 refund and you can buy another power plug. Shipping it back to China is half the cost of the unit, so it is never worth it to get a warranty replacement.
