Picked up mine yesterday and haven't looked back. Very noticeable speed increase. One thing I love about the router is USB mode! On my previous UQ Wimax I had to wait for air port (on Mac) to search for the router. On the Softbank 4G, you bypass that. All you do is connect the router to the usb on your mac and a tiny little interface pops up telling you to click to connect. Done. You can check download speed and signal strength, with the option of choosing 3g! Or, both. Very satisfied customer. And very fast!
