Great for the price!
Size: 14AWG-50FT, Size: 14AWG-50FT
Ordered a spool of wire to install a new light bar and rock lights on my Jeep. Did the trick and cheaper than most other brands.

Decent copper clad aluminum
Size: 14AWG-50FT
If you want the best wire, you should probably go with pure copper wire. It is more expensive but conducts better and thus is more efficient and less likely to heat up. If you are doing a low power, short run of cable, however, this wire should serve your purposes well.
My purposes for such wire are varied. I am a licensed ham, like to build circuits, and have an electrical engineering degree. Depending on the specific tasks I'm on, some I'll gladly use this wire, others I'll go with pure copper.
In comparison to other similar copper clad aluminum wire I've used in the past, the wire is pretty flexible and easy to work with. I also prefer the softer insulation like this has. You need to fit the wire to the job but if you have the job this is right for, it'll serve you well.

good wire for the price
Size: 14AWG-50FT
This speaker wire is of good quality. I don’t know what to say about it besides that its 14 gauge, which is a bit on the thick side, but good for getting high quality sound or for doing long runs of cable. Its not pure copper, but that's not really necessary unless you are an audiophile and even then, i wonder if its really noticeable. The 50 feet it comes with is enough for a 5.1 surround system, as long as your speakers aren’t too far away. I haven't noticed any weird sounds from my system after setting it up with this cable. The housing is relatively thick but not shielded, so I was careful to keep it away from power cords. All in all this is good cable, especially for the price, and I would purchase it again.

Not as good as pure copper, but maybe good enough
Size: 14AWG-50FT, Size: 14AWG-50FT
This wire is copper-clad aluminum, which means you sacrifice some conductivity for a for a less expensive conductor. This wire is very lightly clad with copper - the thinness of the copper coating is obvious from a casual observation (see image).
I measured 4-wire resistance across the entire length (50') of wire - it comes out to 0.34 ohms on each lead. This is a bit less than double what you'd expect from an equivalent length of the same gauge of multistrand copper, so if you're planning on running a long length of this it might be prudent to pretend that you're working with a slightly smaller gauge than you actually are. That is exactly the approach I'm taking with it, and it works well for me within that context.

Great speaker wire
Size: 14AWG-50FT
I ordered this speaker wire to replace my speakers in my car. I highly appreciated that there are 50' included on this spool, it's perfect for rewiring the stereo speakers in a car (or house). The wire appears to be made well and is the correct gauge. The sound quality is great with my new speakers, and I am highly impressed.
I recommend this speaker wire to others, it's exactly what I needed and has met my expectations for high quality speaker wire.
