Excitement about this cable/price. But for smaller projects this is a great product for the price. I read negative reviews before making a purchase decision. The most common negative feedback I've seen has to do with difficulty distinguishing wire colors. In my experience, that's not a problem; Green and blue tones are clearly distinguishable. Also comments on kinking and binding. Again no problem; the cable slides freely from the spool. If you need a cable that requires certification, you may need to do additional research yourself. But for small projects where you only need one cable to get the job done, this product will do. My project was to run cables to install security cameras in my house. Three runs of 125 feet. No cable issues - properly connected and tested - and no camera performance issues.
