The Sensei PRO 43-58mm Aluminum Step-Up Ring permits the use of 58mm threaded filters on lenses with 43mm filter threads. It has large side knurls to provide a more textured grip when mounting or removing it from a lens. This step-up ring features a lightweight aluminum alloy construction that has a corrosion-resistant, matte black, hard-anodized finish for durability and to minimize reflections.

The knurled edges are nice and make it easy enough to remove a filter that got tightened a little too much.
It's good
It is a good step-up ring. I have bought this brand before.
The knurl-like grip distinguishes Sensei from Sensei PRO step-up rings, and makes it easier to unscrew reluctant filters (which you shouldn't have over-tightened!). Heliopan also makes great rings, and in a few more odd sizes (and in brass!) but they're much more expensive, and sometimes special order.
Perfection!
It'd be hard to mess this one up. Simple aluminum step up ring - no issues connecting multiple screw on filters to this ring.
Never really realized how small 43mm is until you have to turn a circular polarizer with gloves on. I have several lens with 58mm requirements. So this was a no brainer. You carry less filters and the bigger size makes it easier to operate.
