I left a review saying this on the book, and Amazon deleted it because they thought my review was fraudulent. Of course, the book at the time had a 5-star rating from fake accounts.
I wouldn't be so certain about that. I've found that there are a lot of sellers selling the same things, but they're not the same sellers under different names, they're just getting stuff from the same places. Often, for cheap things, the source is AliExpress (or Alibaba), or potentially cutting out that middleman and just getting them direct from the companies that sell on aliexpress/alibaba.
It's also been my experience that pretty much _anything_ that isn't a big name brand item being sold on Amazon can be found for much much cheaper on Aliexpress. The exact same product, just without the 1000%-2000% markup.
This is normal.
For instance, when I work on my bicycle, I have to use a $40 Park Tool to cut brake lines and shifter cables. The $40 tool delivers far better results than you could ever get from a conventional wire cutter.
I replaced them with $5 Stanley wire cutters that had 0 issue dealing with guitar strings.
So what happened is I was given a 10c piece of junk and paid $10 for the privilege of being ripped off.

If you ever try to cut a spring, you will get the same issue.
A few people have told you that wire cutters come in two forms: hardened and not hardened, and that if you wish to cut steel you should buy cutters that are rated for steel. The price does not tell you this information. The data sheet for the tool does.
Here's a pair of snips that cost over £50. I'd be displeased if you borrowed mine and used them to cut guitar wire. https://uk.rs-online.com/web/p/cable-cutters/0614766/
One thing you can't see in the images is that these cutters tell you what wire you can cut on them: https://imgur.com/a/Zk3LBCE
If you want to cut steel you need snips that specifically say they can cut steel. These don't have to be expensive: Here are some for £7. https://uk.rs-online.com/web/p/cable-cutters/0732820/
I recognize I don't have the heaviest duty cut-through-anything shears that I could have with more money, but where I'm mainly doing light jobs like speaker wire and guitar strings it's not a problem... unless the snips themselves are terrible.
I don't expect to have to replace the Stanley set unless they become rusty from disuse.
It was just me getting ripped off.
The $5 guitar string tool will work every time, though.
I was irate, having paid $10 for these. So I go online to leave a review and warn people off... only to find that the seller "no longer existed". They absolutely did, and were selling their awful snips but had changed their name and paid for a bunch of 5 star reviews again.
I've been far more aware as of late that whenever I search for something (say the staple gun I recently got my wife) all I get are offbrand or knockoff results showing for often several pages. I have to go, figure out which brands are reputable and then come back to actually make my purchase.
I'd rather just go to a brick and mortar at this point. I'm definitely not renewing my amazon prime.
