none

Durable. Also correct size. Can't go wrong with the price especially for how much you get in the pack.

I've had this product on my main battery for 6 months now and still holding like day 1!

These work great good value worth every penny only thing is if u plan and closing them tight I suggest using channel locks or vise grips

These are great for the price! exact same quality as the more expensive ones, i used these for the big 3 upgrade to my car and they work flawlessly! I would definitely recommend these

Bought a pack of these to keep as spares in case i ever have to use or if friends ever need one, cant beat the price, very good deal.

If you are going to use ring terminals, you should open end crimp style like these and solder them when using 4 gauge to 0 gauge wire. Its a little more work but in my opinion its the right way to go. It does take more time than just crimping them only or using set screw style terminals but if done right the end result is the same if not better so why pay WAY more for 1 set of terminals when you can get 10 for this cheap. It's a no brainer to me, but thats just me.

I bought these because i needed 0 Gauge terminals, other terminals retail for $5-7 per pair! I got a pack of 10 for $12 that includes shipping. You can't go wrong with this buy. Easy to crimp. If you don't care about the one color gray of the rubber thing, then this is good for you.
