If this could fit in my backpack, I’d take it. In a heartbeat. Screw all the Japanese social customs about theft and honesty. Bringing this puppy home would be worth every shameful moment. If the Japanese invent nothing else in their collective lifetime, that will be okay with me. Instead of describing in intricate detail the miracles this device is capable of, I’ll leave the power of your own imagination to fill in the blanks that the Japanese-only instructions on the armrest explain. (Although it’s best not to push said buttons while toilet is in use, it can make for some hard to explain to your dorm mates surprises)
