Yes, it's quite useful around the house. Anything that isn't cranked on tight or corroded typically is fine. This is my go-to for most chores involving a wrench.

The XS is useful even as a small tool in a carry-on. I've busted mine (and it's Cobra XS equivalent which is probably more useful on a job site) out in a datacenter, etc. to get a small job done. You can more or less crank on them with as much strength as you can and they won't break or slip.

I bought it as a laugh when I found one 50% off and ended up purchasing a dozen or so as Christmas gifts for my ops staff that year. Fits in the watch pocket of your jeans comfortably, so it's handy to just have on you all day especially if going up and down ladders.

It won't replace a full toolset for a serious job - but as a "just in case" pair for little quick jobs they are unexpectedly useful.

I then ended up with a collection of around 20 various Knipex tools over the years since they simply are so much better than anything else I've found. Their precision nippers are the bees knees for terminating cat5/6 into patch panels, for example.

Definitely pick up a "baby wrench" if you have an excuse to!
