i recently purchased a single port add-on for my computer, and I must say, it`s been a great addition .My analysis of this product showed that it's an Intel-based component, which ensures optimum performance. It's easy to install and I enjoy the added functionality it provides. However, having only one extra port may not be enough for everyone, depending on their particular needs. Overall, I think this is a fantastic addition to any computer, and I'd highly recommend it..See full review
