Because you NEVER know when you'll need booster cables. When it said "no tangle," that's true"”even for someone as disorganized as myself. It easily unwinds and packs back up very compact. Really good pliable (not hardening) wire jackets with well-made, solid connectors on both ends. The packaging is great too. Mine came with one of the red (positive) terminal clamps being separated quite a bit from the jacket that protects its wire (only one plug on one end, though).. which exposed the bare wire. So I deducted 1 star for that, but was hesitant to, honestly. I've used these several times, and they're flawless and effortless to use!

I bought these to have in a trunk, just in case I ever need them. Well, the need came and they did not work. Even after working the flimsy clamps into the electrodes for better contact, there were sparks only and not enough juice to crank my 4Cyl compact SUV engine. Had to bum a better set of cables from someone to get going... In short, junk and waste of money.

Bought these cables after my wife's car died and I had to knock on 15 houses to find someone home with a pair. So...I figured it was time to get myself a pair to keep in the truck. Anyway, bought these just to have something cheap and effective. I've only had them a week or so and have already had to use them. They're decent (especially for the price) but nothing grandiose. The clamp seems a little thin and doesn't open quite as wide as some of the other cables I've used. Plus they come with a case. Again here, the case isn't very fancy or anything but at least it has one. Still I'd guess that it's the type of plastic that will wind up cracking within a year or two. But the bottom line is that it was inexpensive and it worked. I did mention earlier that the clips are smaller than others I've used. That would be the only reason not to buy these I'd say. If your battery terminals are way bulky then don't get these. If they're standard size you should be fine. Anyway, I hope this helps someone in their buying decision.

Pure junk. I got this in mid august and used it for the first time last night to help out a neighbour. One of the connectors burned right off and no car battery got charged. It was connected correctly. I'm not a mechanic and you don't need to be too figure this out, but nevertheless my neighbour is a mechanic. Will upload pictures soon.

My wife likes to complain that I buy too much on Amazon ... I only buy necessities. She asked why would her prius need jumpers, I told her that it's one of those things that you won't need it ... until your car is dead.

Months later, her car died and if it wasn't for the jumpers I ordered and placed in her trunk, she would've been ass out until I got to her work.
