20 ft 4 Gauge Jumper Cables with Carry Bag– Premium Heavy Duty Jumper Cables & Roadside Assistance Auto Emergency Kit – Exclusive Roadside Assistance Booster Cables 400 AMP – Gifts for New Car

I got the jumper cables two days after ordering. Nice.They replaced a set of much cheaper cables whose rubber jackets had deteriorated substantially and probably became dangerous to use.The set I got from Sarah's Source LLC are hefty. I've already had to use them. One of our cars has been in storage. We're in the northeast, so it gets cold and its battery died. Alas, I didn't back the car into its garage, so I needed an extra-long jumper set. No problem. These cables were long enough to go the length of the car. Started immediately, so enough current was travelling along the 20-foot cable length. Another nice thing about the cables: the handy instructions, right on the cables themselves, just in case you're not 100 percent certain which negative lead goes to the battery and which goes to a good ground. Another nice thing: the handy-dandy bag.The cables are clearly heavy duty and their rubber jacket appears like it will hold up for a long time. And the clamps hold the battery terminals snugly.

I've had lots of jumper cables over the years and these are hands down the best I've owned. Most jumper cables out there work (or can be made to work) so it's the details that matter when choosing one. That's where these really shine. Extra long length eliminates the need to position the donor car in a possibly inconvenient or even dangerous position relative to the receiver. That can be a big deal. The clamps are very robust with good clamping force. Much higher quality clamps than I've had on most previous cables. Finally, the bag is really a convenient, compact way to store the cables in the car. (Why don't all cables come with this??? A very sensible add.) We'll see how they last over the long term, but I'm very pleased with this purchase. These cables with the storage bag hit all the right buttons for me. Highly recommended.

I was pleased with the appearance of the cables when I received them. They are nicely finished and the storage bag is handy. Always hated getting out a tangle of cables when I needed them. I found their finish and appearance to be very good. Also, even though theyre heavy gauge, they're not stiff and hard to manage. The clamps could be a bit heavier but are plenty strong to provide a good grip on the battery posts. At 20' I didn't notice any amperage drop and started my big V-10 quickly. BTW: was amused by the negative review about no starting a diesel pick up. Don't think it was the cables. Most likely either the supply battery was weak or the discharged one was shot. These cables should do the job for just about everyone and I'm going to order another set to carry in my motor home. Buy 'em, you'll like 'em!

I can't give 5 stars because I have yet to need to use them. My father is stubborn and refused to let me buy him new cables even though his were dangerously fraying. I "accidentally" left them out in the open in his truck and was told he was awed that i could find quality cables made "in this day and age." Resulting in every member of my family owning a set now, the heavy duty instructions connected directly to the cables is ideal for my forgetful mother.

This appears to be a great quality product. The cables look to be well made and not cheap stuff. The carrying bag is a great addition to keep the cables confined in the car back. And the glass breaker-seat belt cutter is a bonus we never hope to need, but if we should need it, it will be great to have--if we can find it in the car! We know safety glass will not break easily without a sharp pointed tool. Including this tool is a great idea! Perhaps it should be tied with breakable thread to the end of the drivers seat to be in reach of the driver if an accident should occure and it is needed.

Great set of cables. Heavy gauge wire ensures that they shouldn't overheat and melt the insulation surrounding them. Seems to grip well too. Although I have yet to need them, I feel comfortable saying that I don't foresee any issues with them. The 20' length is a big plus too. Sometimes it's not so easy to get close enough to use the cables. By the way, for those who have them or plan on purchasing cables, there are a variety of sources on the internet that provide quick demonstrations on the proper way to jump start a dead battery using such cables.

This are great jumper wire cables and I thought that the bag is gonna be way too big from pictures of the bag I saw but is a good size it can be fit under the seat and the wire insulator is nice and thick, the gator style clamps are good enough it comes with a small tool sort like emergency seat belt knife in case you get trapped you can cut it out, the hammer to break the glass windows is not so heavy but it will do the trick I mean is not a top of the line but is good enough :)

Although I had hoped to rarely, if ever, use the jumper cables, the opportunity did arise a few days ago. They worked as I expected. In our garage parking situation, when a jump is needed, we must stretch the cables across the full width of two vehicles. And the space between the cars, too. The cables easily traversed the cars and the clips locked onto the batteries just fine. The "dead" car started right up. Afterwards I rolled up the cables and they fit neatly in their bag. If we ever need the cables again, I'm confident they will meet the challenge.
