Pre-lit x-mas trees

Does anyone own one of the pre-lit trees. If so how are they? Do they work good? Are there enough lights? Are they easy to put together? I am thinking of buying one of them.

I posted this on the HOME side too, but I figured there are more hits here.

Thanks

We bought one last year and its great!!! Putting on lights was the one task we hated and now we don't have to worry about it.

Ours has plenty of lights but i know when we were looking a few of the samples did look a little sparse, so just make sure you look at the tree lit before buying.

Good luck!!
