These silicone inverter cables are an investment worth making if you value your car`s electronics. The Screwish cables are top-notch in quality easy to install, and extremely durable .The colorful insulation makes it easier to identify positive/negative connections. The only downside, if there is one, is the high price point, but in my opinion, it's worth it for the added security and longevity. Overall, these cables are a must-have for any car electronics/accessories enthusiast..See full review
