If anything, look for brass chromed mounts on both sides of the adapter. If you complain about the cheap soda can type, the Novoflex is not much different.
That's most distressing. The infinity focus issues you report were with the Novoflex?

I have two adapters for Leica-M to E-mount, a Metabones and a Voigtlander, and I use a Novoflex adapter for Leica-R to E-Mount. The following comments are, of course, specific to my adapters, and there may be variations in other copies.
I tested a Minolta M-Rokkor 40/2 for an infinity shot throughout its aperture range on my NEX-7, tripod mounted with both adapters. First observation is that the Metabones adapter gave perfect focus at the infinity stop on the lens whereas the Voigtlander adapter allowed focus beyond infinity. Secondly the Voigtlander adapter is apparently de-centred - the focus on the right edge of the frame at wider apertures is always softer than on the left. Generally, the lens behaved extremely well and showed excellent centre sharpness wide open on both adapters with good edges but soft corners with the Metabones and slightly less good edges and corners with the Voigtlander adapter. This comparative behaviour continued as the aperture stopped down so that at f5.6, when side sharpness became excellent with the Metabones it was merely reasonably good with the Voigtlander. The optimal aperture for sharpness is f8-11. The best corner sharpness was achieved at f8 with the Metabones producing a very good showing while the Voigtlander corners could only be described as good although both became very good at F11. The Metabones is clearly better than the Voigtlander performing better at all apertures up to F11 and also suffering no de-centring problems. The only benefit of the Voigtlander is that infinity focus is always guaranteed since it can go a little beyond. There is no such flexibility in my copy of the Metabones. This presents no problem with the Rokkor-M but might do with other M-mount lenses. This is, however, not really an issue for me as I rarely do infinity shots on the Nex.
For comparison, the Leica R 50mm F2 Summicron performed impeccably at all apertures with the Novoflex adapter on the NEX and seemed to be at optimal performance by F4, where it matched the Rokkor at F8. Like the Voigtlander, the Novoflex allowed focus beyond infinity.

I ordered a Leica M to NEX Fotodiox Pro adapter from Fotodiox´s webshop after having tried their Leica M-EOS M adapter which I found reasonably good.
I received an adapter which more or less fell off my lens, and after closer examination I discovered that the adapter lacked the leaf springs which were supposed to be in the middle of the adapter to hold the adapter in position on the lens.
I tried to contact Fotodiox about the issue, and only after the fourth try on email/ through their webshop contact page I received a response suggesting I returned the adapter for replacement or refund. Further mails from me have received no response.
I am surprised to see this lack of quality control of the products of Fotodiox and expected to have a replacement sent to me no questions asked. I do not want to pay and wait for an unneccesary return of the defect product.
As I no longer need my Leica M-EOS M adapter I have now transplanted the leaf springs from that adapter to my NEX adapter.

That is disappointing indeed. I have in the past had good luck with the Fotodiox Pro line of adapters. Clearly they are not checking as carefully any more.

I just snagged http://www.ebay.com/itm/171103321711 and quite honestly the fitment is super snug and I'm having zero issues with it. Very pleased for $22. The metal even matches the same pattern on the NEX-6 e-mount ring.

The Metabones M to E I purchased last month is severely (as in, 900 LP/IH center, ~820 LP/IH left edge, 200 LP/IH right edge, according to Imatest) asymmetrical. I guess no one can be trusted 100%. I wanted to buy another to confirm it was sample variation rather than some design flaw, but the rest of you jokers put them out of stock! Who said anybody but me could order stuff for their A7/r? :P
Anyway, trying a Voigtlander - though I'm not happy about the price - next.

Wanna put a Hawk's and a cheap Fotodiox up against it?
