No! Unless you’re cramming for an exam, why would you? To say you’ve read a book you haven’t? And why would anyone want to do that? Hmmm…

Even that is too much work for me

I've never done it to avoid reading the book. But when I was a kid, my dad used to demand I read something and then also give me the SparkNotes and demand I read those afterward. Well, he did that a handful of times, not like daily. The first time I remember him doing it was when he was really insistent I read Notes from Underground. I did, but I didn't like doing it.

I haven't since I had to for a class and I had zero interest in actually reading something assigned

I might follow a summary in parallel to help me understand, but I would want to read the novel in full.

Hvnt

I prefer to read them in full. Nevertheless the short versions can provide a clue about the ones that exceed 1000 pages of litter.

I bought a bunch of Cliff's Notes once, mostly of well-known novels. I guess they're usually used for scholastic purposes, but I just thought they'd be a valuable read. I don't remember how much of them I actually got around to reading, probably like 1 or part of 1. I have no idea whatever happened to them.
