I love the look of this usb hub. We have acquired so many things that need to be charged every night so I needed something that had a lot of ports, but I didn’t want anything big and ugly. This hub is small and sleek and almost blends right in to the table it sits on. My first one had a few ports that didn’t work, but when I contacted the seller they immediately sent out another one, so service is top notch as well.Great product for sure. A great solid build and feels very sturdy works fantastic definitely a great product for all your charging needs amazing quality and a great price you cant ask for morehttps://mobile.twitter.com/US_GIFT_GIANT/status/1144180237200240640
