Not sure if it helps, but I own an Xi3 I won off CBid years ago - significantly less risk of it breaking, cuts like a champ, and is solid in terms of weight and build quality. Still exceptionally sharp. I travel with either a Xi1 or an older Palio - both also reliable and sharp.
I assume you’re referring to the Xo, as I’m not familiar with a XiO, but if it’s the circular one with gears, it looks nice, but I can’t recall many times where the equal pressure for even cuts on each side of the cap has ever been an issue.
