The picture suggests a more accurate tool than what I received. Cosmetic issues aside, the hole in one of the semi-circular levers was the wrong size, allowing the lever to rotate several degrees and naturally slide off the target when pressure was applied. Although frustrating to use, I was still able to get the job done. I'm not sure there's a good one-size-fits-all solution, but it's worth noting that you may need to get creative with using this tool if you're working with a particularly large or small nib.
