I typed on one for at least a year, maybe two, and the end of that time the keys were so wobbly I thought they were going to pop off in the middle of me typing. They're great to be reborn as mechanical hacks though. lol This was the last type of board I had before I discovered minitouches, mechanicals, and got my model f at. I thought they were the bees knees, I got 3 2's and 3 originals. They were cool because the jp versions were fairly gettable, and not many compact japanese boards are available in the states.
