I have one. I like it a lot. I owned a Neos and sold it. I just didn't like the feel in my hand and I kept cutting myself when I field-stripped it due to sharp edges. I didn't like the modest sights. However, many owners really like them.
So far, the .22 kit has been very reliable, though I have had a few failure to feed with some standard velocity ammo. But, very few of these.
I really like the fact that it has the exact feel and handling characteristics as one of my favorite 9mm handguns. That's why I bought it.
