KLEIN TOOLS50900R Conduit Lockout Wrench Set, Tighten and Loosen Locknuts in Tight Spaces, 1/2, 3/4 and 1-Inch, Offset Bends, 3-Piece

I have not used but they obviously work phenomenally great. I liked how small they are and are space savers in the tools pouch

Great tool

The offset comes in real handy in small boxes. One end is for tightening and the other for loosening. It's a little tricky keeping it on the nut. Because of the offset, the wrench tends to want to roll off. It takes a couple tries to get the technique down, but once you get the hang of it, they work well. Each wrench has a couple small embedded magnets in the handle area. All three stick together in your tool box. The different colors help when grabbing one.

Work like a charm. If you are running conduit on a regular basis, come in real handy.

Slim design allows for use in tight area, magnets keeps wrenches together for convenient storage.

Looks cooler than it actually is. It’s hard to keep the tool on the lock ring

Works perfectly can get a ton of leverage

Nice tool to be used in limited space.First time I used this wrench and have a kick out of it.The tools are sticked together with magnet, a good feature.I now buy a $250 veto backpack to keep them, along with other tools.Highly recommended!
