I have a Z0 since about Christmas and may share my impression:
- nicely done and finished.
- yes it has some play, but can easily be aligned when tightening the handle. So, really a no-issue for me, but I understand it can bother some other persons. Level of play depends also on the blade used.
- I ordered it with a KVT titanium handle, nice and light weight, it gives the 40% / 60% (head/handle) weight distribution sweet spot to me. I eventually came to use my Stork Titanium handle instead as I prefer the grip of that one, the KVT being a little slippery to my taste.
- concerning shaving performance and efficiency: that Z0 is really great. I mostly used it everyday since about 2 weeks (with Crown Platinium (6) and Treet Platinium (6) blades) with no major problems, no nicks, no irritations, just clean, fresh and really efficient BBS shaves in 3 passes (the 3rd not being mandatory!).
All in all I'm very happy with it, especially regarding its price!
