If you own a semi truck you need these cables
These are great quality and super convenient. I’ve used them to jumpstart my reefer multiple times without problem and they’re thick enough that you don’t have to charge half and hour before the jump works. I jumped another guys truck once and it was pretty much the same deal. Having a quick connect where you don’t need to try blindly clamping in a tight battery box or even open the battery box is super convenient and it’s a good solid connector. My one gripe is the carrying case could have been a bit larger. It’s a PITA coiling it back up in a way that you can close the lid.

When They Say Heavy Duty Jumper Cables, They Mean it!
After having an experience of our car dying and having cheap jumper cables, I decided to purchase a better pair. I did some research online and ended up deciding on this pair through Amazon. They were described as "Heavy Duty", so I decided to give them a try. These jumper cables are a thing of beauty! You can tell just by the weight and size of these cables that they can handle any situation you present to them. I would say the quality was way above what I was expecting, I have used them several times in various weather conditions and was very pleased that there seems to be no loss of power from battery to battery. The storage bag that comes with them is a nice bonus. I think for the price, the value is first rate!

Check the instructions
I was not disappointed by these cable as they were exactly as described and worked well. The carrying bag is rooming and the cables feel sturdy and well made. There are two things I want to point out for your consideration.First, the protruding extention of the clamp teeth may make it more dificult to attach to your battery. I'll add a photo example later to demonstrate.Second, and this is significant, the instructions on the bag have the vehicles reversed. The instructions attatched to the cable are correct. Please be careful when connecting the cables to follow the right attachment sequence.

Great zero gauge wire and good length
Truly amazing product. First of all, this is truly zero gauge wire. Second, it's long enough that you could. Yes, jump from behind a vehicle, without having to pull it out of a parking spot.
