1 star missing because it doesn’t really work well with the Takumar 50 1.4 (the lens doesn’t focus to infinity as others have mentioned). The other four stars are because otherwise it is built well and I’m sure will work with most other lenses. Using it on a Sony A7R III and it gives me nice and sharp images even with that sensor so well machined I’d say. Although I also have the same brand adapter on a Fuji XT2 and it still focussed to infinity (though it did get a little stiff at that end) so I’m not sure if they’re all manufactured exactly the same or it there is a difference from version to version. All in a all a good product.

It does what it says it does. I just don't think its worth anything over $20 as you can buy the same product on ebay for far cheaper. But it adapts M42 lenses with no issue.
