One of the bus bars is missing all 4 nuts which makes it pretty much useless did give it 2 stars because it’s actually a really nice good quality product but considering only half the product is usable it’s a 50% Failure I would change and give it more stars if the problem is resolved by seller. Did the exchange through Amazon. And while I had no contact with the seller it was promptly exchanged with no hassle. Overall it’s a very nice and robust buss bar I have no doubt it will do its job now that it’s complete. I’m really happy with it

Great bus bar but the top could be sturdier. The top can only be tightened finger tight. Without the top, anything can short out the battery.
