Good to know the post Minamoto Kobayashi full history details and that it has had 4 owners.I was the owner after Minamoto Kobayashi sold it to me. And after me this laser had another owner, who then sold it to the current owner. Buying this laser you'd be the 5th owner. Please be aware that it may have some flaws. At the time I still had it it was still very good, like new. But I remember the person I sold it to (I believe it was Podo) said it had a rather wide beam which he didn't like. Don't expect to get to get a very low divergence and thin beam like Optotronics lasers with this. It's a great unit but in my opinion more of a hype than it actually is amazing. Also, OP saying this laser hasn't been used for 2-2.5 years is a straight out lie. I bought the laser in december 2014 and I sold it around summer 2015. This would be around 2 years from now. However, I sold it to the owner previous to the current owner. So unless he turned it on just once, or not at all, this laser has for sure been used within the past two years.
Good points +You'd think if it was such a great laser pointer it wouldn't be resold so many times, but from what I've been able to gather, it is a well designed unit.
