I got these to use with a 77mm filter so I could use it with all my smaller lenses. The threads seem fine and they are doing everything I expect.Can't go wrong at this price!

the ability to step up or down you filters is a huge money saver and for that purpose these don't disappoint.They're sturdy & well made, work perfectly and essentially do their job as advertised. My only critcism is in the packaging which being just a plastic sleeve, is a little underwhelming. But to be fair, these are very simple and cheap accessories. All in all very happy with my purchase as I'm sure you will be if you pick these up.

Well made and not had any issues so far. Threads are nicely milled. Even with my greasy sweaty fingers I've not struggle to screw and unscrew

Bought a whole set of filters and realised that not all lenses are the same. This saved me buying a further set of filters in a different size. I only use one of the rings but it saved me a huge amount of money. Build quality is great. remember always turn opposite direction of way to tighten before you tighten to ensure thread alignment. Finger tight no need for muscle

I used this to fit the mounting ring of a macro flash ring to a lens with a different thread size. It is perfect for something like that.

I'm giving this item a 5 * because it is well made. The metal quality and finish appear to be very good and I couldn't fault it from close inspection. Unfortunately, I have to return mine as it was not suitable for my purpose. I bought a 82mm ND Filter to use with the step-up ring stack hoping that this will be a "one-size-fits-all". Unfortunately, there was just a blob (of darkness) in the middle of the image especially at wide angle. The considerable distance built up with the step-up rings between the lens and the filter may have something to do with the blob. I just couldn't get an edge to edge ND on my image. I reckon that the filter would be OK if used without step-up rings.
