## Customer Reviews

### ⭐⭐⭐⭐⭐ The best bus bars I've found
*by E***N on December 5, 2015*

These bus bars are SUPERB. They have a lot of copper in them, as they are a bit heavy. I purchased the 12 x 3/8 for an extremely good price here on Amazon. Well built, and you can combine two for a negative and positive bus on one bar. The covers are semi-clear and very durable. As shipped they snap on. I will say, they are not easy to remove with just your bare hands. It appears you can also use screws to attach the covers. Extremely little to no resistance across the bar and from the farthest terminals; my multimeter had trouble detecting any.The larger terminals are perfect for interconnecting batteries in parallel and connecting large inverters, while the smaller ones are great for attaching small meters, direct-voltage lighting, or accessories. And at 1000 amps, I have yet to be able to throw enough amps at it to even come close to its limits.I use these in a solar system as a default point of connection for my battery bank, charge controller, inverter, and for lighting/accessories. These have quickly become the very heart of the system as all power passes through these.Highly recommended.

### ⭐⭐⭐⭐⭐ Solid built power bar.
*by R***M on October 13, 2019*

Very substantial power bar. There is no question as to its robustness. We’ve actually drawn 1400 amps at 24vdc for short duty cycles without any issues.

### ⭐ Works as advertised but WAY TOO PRICY for what you get
*by A***R on September 8, 2020*

$162.04 is just WAY too much for a machined piece of metal with a few studs and screws with plastic end caps Isolating the power bar. If I could go back in time I would NOT have ordered this and just made my own common power points with some wood and bolts. It would have saved me hundreds of dollars.
