This little kid saved me a lot of frustration with my Lenovo Yoga 2 and its unforgivably awful internal Wi-Fi adapter, which can be twenty feet from a router and only two gets stripes. I love the computer the most and don't want to return it just for Wi-Fi, although good Wi-Fi is a MUST. With this adapter I was about 75 feet from the router and had a full signal even with two extension cords (6 and 3 feet) plugged in. Unless you keep it on your desk right next to your computer, an extension cord is a must. I would give 5 stars if it wasn't difficult. But there's no problem putting something heavy on the cable at the base to keep it from falling to the ground and breaking.
