Some cheap CAT wire that was apparently run in the early 2000s was only 2 pair inside the jacket. This will quickly sniff those out of your network.
The real tester I'd want/actually get use from are the super expensive ones that can show the twisted pairs out of order (or specific conductors which are at fault) between ends. I have had one defective run of cat5e which had a break in the length of the cable that it would have detected.

That's a problem now with 1Gb installations. And it's a pretty common problem, though it seems it starts in homes built in the mid 90's when broadband was majorly rolling out. The best ones are the ones that the builders ran the ethernet cable and the electric cable together through the walls.

About this product:
Not a bad tool but IMHO most home owners and DIY'ers that won't be doing this for a living would likely be better served by something cheaper like this: https://www.amazon.com/dp/B08RNDBQRX. It also shows a breakdown of EACH wire, so more feature for less $. I have about a 1/2 dozen of this type I've been using for 10+ years, pretty sure I got them on clearance from monoprice for under $5 each.
On the flip side, if you're an up and coming IT person or you're that guy/gal that everyone calls for IT problems you should consider a tool that will do more. Something like: https://www.amazon.com/dp/B084LKVBM5 will cost you a little more but adds several more useful features such as tone generating. Nothing worse than showing up to someone's office that has 20 unlabeled network connections and you need to figure out the one that's bad.
On the subject of 2 pair ethernet? There was a standard WAY back in the early 90s (is anyone old enough to remember that long ago?) called CAT3. It was 2 pair, just like phone cable, but shielded and twisted, i think, i forget the exact details, feel free to google it, but I think it was designed for 10mbps, but often capable of 100mbps. As for homes running it or even CAT5, sure some may have. It's very doubtful that any rando home would do it though. Home builders use the CHEAPEST everything to pad their bottom line and the expense of swapping super cheap phone line up to CAT3 or 5 or in today's world 5e or 6 would probably be at least a couple thousand $ difference. Though, I did work for a family in a ~2million $ custom built 3500sq foot home once and the owner told me the builder used CAT5 for all the phone lines so he would have "network" when he wanted it. I took a look and the builder ran the CAT5 cables just like phone lines, all went to the box outside all twisted together in standard phone line box. Also there wasn't enough slack in the lines to pull them out and terminate them into network keystones. Probably could have been done, but sure as heck wasn't "ready".
