We bought a Noma brand tree with coloured pre-strung LED lights 5 or 6 years ago and have been really pleased with it. One light has burned out and the rest still work. It's much easier to use and I don't have to deal with the wrapping and untangling of lights, just plug section A into section B, and section B into section C after the pieces have been put together. My Mother in Law was so impressed with the ease of putting up and taking down the tree, she replaced her old one too!
