NiSi V6 100mm Filter Holder Kit with Enhanced Landscape CPL Filter

First off, I love Nisi filters. I had V5 and loved it. I love all their filters and will keep using them. As soon as I can, I'll upgrade to V7 or downgrade back to V5. The problem with V6 vs V5 is their addition of a secondary screw tight locking mechanism. V5 didn't have one. V6 added it. And V7 implemented it differently. V6 includes a sticker warning the user to make sure it's operated exactly correctly. That sticker is clearly there because people started breaking their filter glass. Which is exactly what happened to me. It happens when you think you're locked onto the ring but you're really not because the locking mechanism isn't open enough to allow a secure 'click'. This is such a change and so unintuitive between V5 and V6. Yes, I should have made sure it was locked but clearly, because the sticker is there, that the engineers realized the mistake and tried to fix it by just warning customers. And since V7 removed it, it's clearly a building mistake. So I blame V6.
