Cable quality is very good.  Insulation is thick, connectors are not flimsy.  I'm using these with my Nexus 6P and I'm very please.  Sometimes with cheap cables, they get loose when connected to your device, but these fit firmly.

Cable insulation seems thick, and cable looks to be assembled properly. Noticed immediate performance increase when transitioning from unbalanced cables to these balanced units. Noticeable decrease in noise and increase in signal level.

This cable is very thick and feels substantial. Highly recommended. I like that it is a 3 prong plug which makes it good for plugging in computer equipment or appliances.

Pros:
-Tight Connections
-Strong cable
-Thick Construction

Cons:
-Most likely has thin cables in the center (not a huge issue, just don't compare to Monster Cables)

TL;DR - high quality thick cable that supports USB3.0 speeds, wish the plug could be stronger though

Bought this as an extra cable for my Samsung Galaxy S5. Cable came and was surprised at its thickness and quality feel. Charged my Galaxy S5 quickly without incident, no overheating in the phone or cable. Since it is so thick the ends and bends in this cable don't feel like it will break it. Which is great because charging cables, especially for phones, can get quite frayed with use. No issues to report after 1+ year of usage.

One thing to note that I wasn't quite pleased with:
- The plug to the phone is somewhat wobbly or loose. If left undisturbed, the phone will charge just fine, but will frequently lose connection if moved around too much while plugged in. Not a big issue, but could be for some.

quality cable that is a little thick and the connectors feel strong and durable. would not hesitate to buy again.

Very good quality cable. Rubber coating is thick without being stiff, and is very supple so as not to crack or split. Has a very 'Beats Audio' look and feel, so if you need an extension for those products, this is a pretty good match in look and quality.

Well made, thick insulation. Not your average thin cord. Great for long long distant plugin's where the plug is not near you.

Amazing cable quality! These cables are build like tanks.

Cable works real well.  The quality is very good.  I like the nylon braid
(I think that's what it is) for the outer cable jacket.  Much better than
rubber/plastic cables.  Seems like good quality connectors.

Extremely high build quality with braided cable. Very solid.

Long cables, good connectors, high quality. They stay put nicely. They seem a little on the thick side though.
