1) Ready to use; 2) no warranty for electronics that may burn out if surge protector fails. There is no trademark on this product. If you search, you can find similar products from well-known brands at slightly higher prices. Yes, similar products that also have side-pivoting end caps (which is a great feature). From other reviews I see that some devices work and customers are happy. But other units like the ones I received. My recommendation is that you look elsewhere. And if your electronic equipment fails due to a faulty surge protector, look for one that actually meets its surge protection requirements.
