I own the adaptimax and it is solid billet bulletproof with very tight tolerances...zero slop that I can tell. Its also much more precise in aperture adjustment since its a thumbscrew. The only caveat is you need to make sure the screw is out enough before putting on some lenses or it scrapes the housing of the rear element in some lenses...no real damage but just something to be aware of when using it.
I also have the voightlander and the adaptimax blows it away. Its black chrome plated brass for the main body, stainless for the m4/3 socket and nickel plated brass for the adapter to nikon lens socket. Also the lens socket can be tweaked if an even tighter fit is desired...or you're using worn lenses. Very top notch and I'd buy it again, but something tells me I will not need to...ever!
