Adapted lenses K mount with macro focusing helicoid recommendations

[kayakfari]

Hi all, new to Sony E mount, just got a clean used NEX-3N. Looks like a fun and capable cam, albeit still getting used to the controls (coming from Pentax land).

Naturally I'd like to use my K mount lenses, got the basic adapter. Now I'm thinking I could easily add some macro functionality to all those lenses by getting a K adapter with the focusing helicoid.

Any recommendations on these adapters? I see there's a Kipon, kinda pricey. But on Aliexpress found a no-name that looks identical but at a fraction of the price!

Anybody have experiences with this one?

Thanks!
