The first one never worked right,it would runaway trip upon start up. Through many email exchanges with Felix and multiple phone calls, I was able to exchange it.The second worked better but over time (still within a years time)it developed where it would not work at times at all. I suspect of wet muddy conditions that I was using it in.Eventually,it fell apart,the plastic and aluminum components separated into individual pieces which is probably why it would get wet in the first place and not work.The worst product I ever bought, worst customer service I ever experienced. Since then, I sold my t2 classic and I will not have anything to do with the company's products again, the $130 was a bittersweet lesson.There are better companies out there.I wish I could tell you about their customer service but I haven't had a single problem since the f-pulse product.The XP Mi-4 pointer is a whole lot better than the f-pulse for me.I also use the mi-6 pointer connected to the XP deus but didn't like to disconnect its pairing to use with the Nokta/Makro machines, therefore I added the mi-4 for those machines.I really liked the t2 classic but the whole pointer/ customer service left an unpleasant experience.$130 isn't a lot for some but it is to me.
