I LOVE my Xikar. I have the Xi3 Spectra..and it works great! I have noticed that without a cigar in it, one side closes first, but as soon as there is resistance (aka a stogie) it cuts nice even.
The best technique I have found is placing the open cutter flat on a table, putting your cigar in so the head rests on the table, then snipping...perfect cut every time. This works best with parejos, but can work with figurados as well

Just an update.. I got my Xikar Xi2 back, and here's what I have to say about it....
I know this has probably been beaten to death, but I just wanted to chime in here and say that Xikar's customer service and warranty is TOP NOTCH! I sent my Xi2 cutter in, because about a year ago, the spring action when you opened it wasn't working, and you would have to literally pull the blades apart.. Well.. Long story short, I bought a Palio, and started using that, and my Xikar sat around until about a week ago, and I decided I was going to send it in to have it repaired. I threw it in a padded envelope with a note letting them know what was wrong with it. In about a week, I had it back in my mail box, good as new. I don't know if they fixed it, or just replaced it, but I used it tonight at the cigar shop while shootin the crap with some of the guys, and man its like a whole new cutter! I had a couple friends use them on their smokes, and they all complimented on how nice and sharp it was! Thanks Xikar!
