Review on 🔧 Pentair OMNIFilter OW70 Strap Wrench: Universal Tool for Water Filter Housing's Maintenance and Removal by Jeremiah Whiteley

I bought this based on the drawing and guessing this would fit the Omni-Filter U-25 model. Far from matching the picture. Instead of 12 internal tabs to engage the 12 holes on my clear plastic U-25 filter cartridge, this product, marked OW40 on the paper label and SW-2 on the black plastic key, has only 4 tabs. It's useless to me (although I'm sure it works with other filters). The picture on the Revain website looks like the blue plastic key I'm trying to replace - this black plastic SW-2 key is something else entirely.
