They do the job but they don't screw on lens very easily
They are good and serve me well. I have many filters all 77mm size, I have used these adaptors to fit my filters to 67mm and even 49mm lenses, it works well for the purpose. However, they don't screw on lens very easily, you have to align and realign many times until you get it right, something that never happens to me when I am using my decent quality Hoya and B+W filters (I think I saw somewhere that aluminum is not a great material to make precision screw mount, expansion with heat would affect alignment, so you'd expect this from cheap quality stuff made to serve basic job, brass would cost way more which is what is used in B+W filters). I would recommend these except in two cases: you need to use them constantly, or you can't afford fiddling with these during an important shoot (please note I am a hoppiest not a professional so my advice is based on my needs).
