Good quality and length adequate for charging from another car.

Read the reviews, and these are at the top of the list on a couple of review sites. Nice and long, very supple/flexible, with sturdy clamps. Thought the length might impact charging capability but they work like a charm.

Appear to be very well made. Good quality storage bag that is appropriately large, especially if you take the time to carefully coil the cables. A pair of gloves with gripping buttons on the face was included, a nice "extra" that you can keep in the bag with the cables and use to keep your hands clean. Instructions for use are on tear-proof label permanently attached to the cables in case someone with marginal experience or intelligence needs them. I haven't yet had to use the cables, but based on what I've seen for sale in local stores for the same price or more, these are excellent cables and a very good value for the money. I was a little concerned that when coiled, 16 footers would be too long, but my worries were unfounded. I think they're just fine-- don't take up too much space. I keep them in the compartment with the spare tire. I can recommend the cables and would buy them again in a minute. I think they're a good value for the price, which was $15.99 (Feb 1, 2018). The only reason I didn't give them a 5 star rating is because you are supposed to give 5 stars to products you "love." Can you really "love" jumper cables?

These are clearly much better than the typical ones found in an auto parts store. I purchased these to keep in my RAM. The more common, smaller gauge cables at best struggle to boost the heavier batteries found in these types of vehicles, so heavier gauge cables are a must. I see some ridiculous reviews complaining about the cables being copper clad aluminum as opposed to solid copper cables. That's simply an example of having a little, but not enough knowledge. The Service Entrance cables from the utility pole to your home are strictly aluminum - not copper and not even copper-clad aluminum. For the person looking to boost most types of vehicle batteries encountered, there's just simply no need for anything more than these. These are "heavy duty" in the sense that they are a larger gauge than most of the more commonly available smaller 6 or 8 gauge cables found in retail stores. (Reminder...the smaller the number, the larger the gauge and thicker the wire....4 gauge is thicker than 8 gauge). These are built well and the handles are insulated well. The clamps are versatile and can be clamped straight-on or from the side, accommodating most battery post styles. The additional length is a huge plus, especially with a larger vehicle such as mine. You don't have to worry about positioning the vehicles just right to use them like most sets of cables, which is sometimes difficult when a battery dies. They came with a pair of gloves and a small wire brush for cleaning terminals. Not essential, but a nice touch. The carrying bag is sufficient for a typical few-times-per year use, and the cables should provide years of use if stored responsibly and not used to tie-down cargo or if hastily rolled-up, tangled and thrown in a trunk like most lazy people do. If you are performing recovery service you would need a more durable carrying case. Another thing....they are not intended to be pulled-apart, as the jacket is not perforated and will likely tear and expose the conductors. I see other reviewers peeled them apart and then complained the conductors become exposed. It's like peeling apart the cord on your laptop or table lamp - why would you do that? Just because you see a line between the two, doesn't mean you can pull them apart. If you want cables that are completely separate you can find and purchase them that way. Not sure why someone would alter a product then ding it for failing. I wouldn't pay much attention to some of the over dramatic negative reviews or the one's complaining about copper-clad vs pure copper conductors. Those differences are applicable for precise electronics where every watt and milliamp count and extreme efficiency is needed. Boosting a battery requires sufficient voltage and current for a relatively short time and nothing more. And besides, do you know what these would cost if they were pure copper? I spent 10 years in the electrical trades and now do design work which entails calculating current, voltage drop and ampacity. In my opinion and experience, these are a good purchase overall for what they're designed for. NOTE: I purchased this item on Amazon for full price and have no affiliation to the seller. I try to write helpful, unbiased and insightful reviews because I also read reviews prior to making my own buying decisions. I notice many reviews lack helpful information, are not well written or give poor reviews based on not reading directions, inexperience or failing to read the product details prior to purchasing. Writing valuable reviews helps pay it forward.

Arrived promptly, which was good because I used it twice in the next 48 hours. Easy to use, clamps worked well, 20 foot length came in very handy. Price was very reasonable. Would definitely recommend this product.
