I have used it for my trip to Japan this March. My review, speed is good and coverage is good as well. most of the time I can get with full speed except arashiyama, but its considerable okay since its mountain area. However, I would recommend you to get the router from them one or two day earlier before your departure. During my trip, they havent open their counter in KLIA2 yet. So, I have to wait for them to pass me the router and somehow they only reach KLIA2 one hour before my flight. Frightened me out as I thought I almost couldnt make it to my plane. BTW, their main office is around KLCC, so if you happen to be working nearby, then might as well get the router from the main office.
