I have this filter as well as the 58 to 77, 62 to 77, 68 to 77, and 72 to 77 adapter rings. It's perfect for all these configurations. The filter is of excellent quality.
However, with the 77mm adapter ring, on which I put the 77mm filter, the ring isn't thick enough, so when you turn the filter, the magnetic bank rotates, and the filter also tends to fall off.
In short, if I had to do it again, I would have gotten an 82mm filter and all the adapter rings to the 82mm.

Overall a good quality filter and the variable ND range is very handy for when I just need a small light reduction compared to using the ND1000. The only drawback I've found is that when adjusting the variable ND the entire filter tends to rotate alongside the adjustment ring, so stronger magnets to keep it in place a little more firmly would've been good. The magnets are more than enough for the Filter to remain securely attached to the magnetic adapter though.

I just got a new lens, needed a 77mm filter to protect it. I'm not going to sit there and tell you this glass is better than any other glass. I just got it and I'm not an optics expert. But I can tell you that the packaging was beautiful, the filter housing, one of the best I've seen. It's circular in shape and holds various sized filters with slots in an internal holder. Much better than the big square thick filter boxes I have from other brands. But, the killer was the filter being so thin, and having 2 areas that are nubby so you can grip it, while the rest is smooth, a really nice feature. It looks right at home on my Canon RF24-105/4 L IS USM. I didn't notice any difference in focusing speed or aberration, but again, I'm not a lab. I'm pretty happy with this brand. I wasn't expecting that.

Expensive but very practical, what a joy to install or remove the filter in a few seconds and with one hand. Technically speaking, I will update the comment, for the moment the weather is not nice enough...

Though I received the order after 12 days of ordering in India, I personally feel it was worth the wait. Still have to test in real world scenarios, but the build quality is pretty good and solid and getting delivery free was icing on the cake.
