I busted the cheap plastic wrench that came with my iSring filters. Was not sure how to get them off, found this tool on internet search for how to. Great advice, great tool. I thought I would still need more help. But once I put the real torque down the filter stared turning. Believe me it was on to stay. I put an extension on my breaker bar, and this strap didn't slip or flinch for a second.GREAT TOOL....
