Well, I own one two (regular Perdix and one AI) with an AI o n the way, soon to be 3 (back down to 2 when I sell my regular Perdix). I'm sure some people hate me, but for different reasons most likely!LOL That is true. He has now made it absolutely clear that he just hates Shearwater and anyone that owns one. That's is just very childish attitude.
In all seriousness, people like what they like. While I don't agree with the sentiment that Shearwaters are bad products (as now with the Peregrine, they do serve the entire dive population with solid products), it is his prerogative to have his own preferences. I won't ever understand why he feels the way he does, but it isn't a legal requirement for me to do so.
