I don't like it. I don't like the sound-- I was going to say I don't like the ayn sound but I have Zayn on my list. But I think ayn combined with zlee is just uck. For a boy too. Bleh all around. I'm not opposed to unisex (I think name trends are heading that way), but this one is nms. I think it sounds more feminine than masculine though.
If I had to use it...
