When the adapter arrived, the first thing I noticed was very solid construction. It mounted to my FS7 with no issue. Not too tight, as I have experienced with some of the higher end adapters, but no play in it either. I have 3 FD lenses - a 50mm f/1.4 SSC, a 50mm f/3.5 Macro SSC, and 135mm f/3.5 SC. All three lenses mounted to the adapter with no problem. Again, not too tight, but no play either. The aperture lock ring works perfect.
What's to be seen is how long the adapter will last. But at such an affordable price, I'm not too worried about it.

Technically, it slightly overshoots infinity but the issue is easily corrected by dialing back the focus ring just a tad --- Not exact but clearly better than not-at-all.
Although very light due to extensive aluminum usage, the build quality and fit-and-finish of the adapter is superb. Connections on the lens and camera mount sides are tight and precise --- absolutely, zero slop. The top of the lens release button is flattened making the lens removal process very easy and comfortable.
Other notes:
- There are no electrical connections so focus and zoom must be done manually on the lens itself
- When mounting the lens, turn the adapter clockwise till you hear a "click"
- Tested with a Minolta 85mm f/1.7 Rokkor-X MD lens mounted to a Sony a6000 camera
-----------------------
Part 2 - Nikon Ai to Sony NEX adapter
Edit: Based on my positive experience with the Minolta MD adapter, I also purchased the Nikon Ai adapter later.
As with the Minolta MD adapter, the Nikon Ai version focuses beyond infinity a tiny bit. Fortunately, the same solution applies - dial back the focus ring and the horizon will become crystal clear. The build quality is impeccable and the finish is smooth and clean of burrs or machine marks. Connections on both sides are taut and precise with zero play.
Additional notes for Nikon Ai adapter:
- No electrical connections present so focus and zoom must be done manually on the lens.
- Unlike the Minolta MD adapter, mounting the lens for Nikon adapter requires a counter-clockwise turn until you hear the "click" of the locking mechanism
- Tested with a Nikon Micro Nikkor 55m f/2.8 Ai-S MF lens mounted to a Sony a6000 camera

2) All of my Zuiko lenses can be focused more closely than on an OM body. This somewhat compensates the Infinity-focus problem. :-)
3) All of my vintage zoom lenses lack the resolution that can be captured by the Sony a6000 24MP sensor. They are just soft, even in the center at f/8, even though they were mire than acceptable with film.
4) Only five of my Zuiko primes are up to the task: 50mm f/1.8, 50mm f/3.5 Macro, 55mm f/1.2, 200mm f/4 and 300mm f/4.5. The rest are too soft, wide open, but ridiculously better at f8. The 50mm f/3.5 Macro and the 200mm f/4 are spectacular with the Sony a6000 (at 77mm and 308mm equivalents).
5) The OM to E-mount adapter exacts about a 1/2-stop loss of speed from the vintage lenses, much as would any extension tube. It's not a problem, thanks to good high-ISO performance.
6) Many lenses made for digital sensors are designed to deliver the light as perpendicularly as possible - to avoid the CA (chromatic aberration) "purple fringing" seen with lenses that were designed for film. I'm getting a lot of CA in the corners of the frame, but it's easily fixed in Photoshop. Note: There's no CA by shooting at f/8 instead of wide open.
Lastly: I later bought a Fotodiox adapter and a Fotodiox Pro adapter for comparison and find them to be essentially identical in quality and function, so far, except the blades that engage the adapter to the camera body are about twice as thick with this K&F Concepts adapter and the Fotodiox Pro adapter, where the blades for this Fotodiox adapter are quite thin - which leads me to believe this K&F Concepts adapter (or the Fotodiox Pro adapter) would be the better choices when mounting a heavy lens (or perhaps any lens). Otherwise, the most significant difference is their weights. The aluminum and brass K&F Concepts adapter weighs 3.5 oz. The aluminum Fotodiox adapter weighs 3.2 oz. and the Fotodiox Pro weighs 3.1 oz. See photos...
All three adapters have a length of 33mm, from the body mount to the lens mount, and again, they all focus well short of Ininfity.
Again, the blades that engage the adapter to the Sony camera body are the same thickness for the Fotodiox Pro and the K&F Concepts, but are much thinner (for some reason) with the Fotodiox adapter. Oddly, they all feel the same when attaching lenses or when attaching to the camera body.
If I had to do it all over again and money were no object, I would get the Fotodiox Pro, due to its being the lightest of the three at 3.1 oz. vs. 3.2 and 3.5 oz and having thick blades, rather than skinny blades. But the K&F Concepts comes out on top for having the best price, the thick blades similar to the Fotodiox Pro, but weighing 3.5 oz. instead of 3.1 oz. I would avoid the Fotodiox adapter due to its thin blades, where attached to the camera body - they do not inspire confidence. Again, the blades are thicker with the Fotodiox Pro and this K&F Concepts adapter.

Top reviews from other countries
The build feels super sturdy. Doesn’t feel cheap or flimsy, which is great. I was kinda worried about attaching my Helios to the camera, but this adapter made it easy. It fits snugly and securely, so I'm not stressed about the lens wobbling or anything.
Installing it was easy too. Just popped it on my camera and the lens, and voila, ready to go. It’s manual, but that's obvious since it's for old m42 glass
So, if you're looking for a good adapter to use old lenses on your Sony, this K&F one is a great pick. Works flawlessly, feels solid, and it’s not too pricey. Definitely a good buy!
Detto ciò K+F lavora bene ed I suoi prodotto sono sicuramente un filo sopra la media dei concorrenti. Ho resistito all'impulso di spendere 10 euro in più per avere la versione forse più moderna con la righina arancione che tanto sarebbe stata bene con la mia A7RIII. Ma, e lo dico sopratutto a me stesso, pensa a fare delle belle foto, invece che stare lì a menartela con l'attrezzatura, che questa è 100 volte meglio di quella dei più grandi fotografi della storia, ma sii curioso, scatta, scatta anche in analogico, non essere pigro e non stressarti per il bokeh, l'autofocus o la perdita di nitidezza ai bordi a tutta apertura. Ora bando alle ciance e vediamo questo cinquantino yashica come rende in digitale...
