My dad had one, i think. I recall using it a few times, and it was so-so. My biggest issue with it was that the head was so large it frequently wouldn't fit wherever you'd need it. Also, didn't really have the strength to handle a really tough nut/bolt like one that was rusted, etc.

Interesting story though.

Literally this.

My dad has two, both slightly different in design. They're not bad for leg bolts, but not much else. Like nman said, the head is really large, so if you're planning on using it in a backbox, you might run into room issues. Also, the head part is very "thin" so gripping things dead on can be a challenge unless you can rest the tool against whatever the bolt is screwed into.

Cool in theory, clumsy in practice. Stick with a decent socket kit, imho.

Just bought one the other day. Yep, sockets would be better. But I was in a jam, couldn’t get the head size. And it worked like a charm. Handy to have even with the above limitations

And I did not realize he won his lawsuit. Good for him. Didn’t think he had a a chance.

Unfortunately I've used one... I have a friend that likes "as seen on tv" tools like these. I had forgot my tools while out servicing a machine and had to use this thing. It's like a crescent wrench, not really ever the right tool but was ok in a pinch.

I Keep 2 sizes in the tool box....very handy, but not much use in pinball.

When it comes to gimmicky tools and pinball, I've found a "dogbone" wrench to be invaluable. With 8 "sockets" permanently integrated on a slim tool, it's perfect for leg bolts because somehow there's always an oddball at pickup. And it's great for head bolts too - its sufficient clearance and gimbal heads allow it to swivel clear of any obstacle in EM to Sys11 heads. Its size allows good torque, and is big enough to not lose unlike a smaller ratchet / socket assortment. The magnetic button is handy too.

My in laws gave me one years ago and I never could find a good use for it... They suck for cars. But with pinball, it's become one of the top tools in the box.

Not a fan of most of the new gadget tools, I prefer a good old fashioned socket or a regular wrench and not the one size fits all wrench, I do feel bad for the inventors as Sears clearly stole there idea.

The "Dog Bone" wrench was mainly used in the 50's and 60's for use on bicycles. There was a leather bag that attatched to the back if the seat. You would carry a Dog bone wrench, pliers, 2 screw drivers and a tire patch kit. That would cover just about any repair needed.

did not know about the dogbone... I have to get one of those.

Dog Bones are great for doing oil changes I have a metric and standard so when you get under that car you always have the right size

Never been a big user of universal tools -- just not specific enough for the application I usually need them for.

I do keep one of these at the bottom of the tool box:

I prefer the slide adjuster over the thumb roller. Sometimes it helps out on an odd size or if I need a bit more torque on a smaller bolt/nut.

I find that most of these oddball universal tools do a lot of things poorly but nothing well. I just stick with the tried and true tools. There is almost always a proper tool out there for the task at hand.

This, but get the HF version. It fits perfectly in the glove compartment too, so I am never at a need for tools to assemble or disassemble a machine in a hurry. For those emergency situations.
