I had the kind with 8 slots cut in a ring. It was clumsy, and I couldn't see what I was doing. It was easy to get the wrong slot. Working by touch, I'd have to stop to think about which way to turn it.
I bought this one hoping to eliminate those problems and because the "box" opening looked better than a simple slot.
I did all 128 spokes on 2 ebikes. Adjusting one spoke changes the tension on others, which I check by sound. This wrench makes a good hammer, so I could adjust and ding without changing tools. Because I could see the wrench on the "nut," I had no trouble visualizing which way to tighten or loosen. The "box" opening gave me a stronger feeling connection than a slot, and the length of the wrench let me see just how far I was turning it.
The ring wrench was awkward enough that I preferred to turn a bike upside down, which entailed moving the mirror, display, and switch. The new wrench is handy enough that I can simply lay a bike on its side. After adjusting spokes, I checked each rim by bracing a stick against the fork or chain stay so that the end of the stick dragged lightly against the rim, then turning the wheel a revolution. All were true. If I'd found runout, the new wrench would have made it easier to fix.
I put a 30" dog tag chain through the hole in the wrench. I'll know by touch which end is which. It should be easy to find if I drop it, and I can hang it on the wall.
