Once I CAREFULLY hung them up, they look and work great!  The bulbs are fragile (as previously mentioned in other reviews), so I highly suggest buying replacement bulbs, as I did.  I broke seven bulbs while hanging three lines.  They can be connected end-to-end so you don't need multiple extension cords to light them all.  The atmosphere on my deck has increased 100% when I turn these lights on in the evening, can't wait to be out there every night.  I am worried about taking them down (breaking more bulbs) and storing for the winter
UPDATE - After one month, they no longer work!!!  I've had them on 5 times!  I've had to change a few more bulbs because of storm damage. I've checked all my connections, etc.  I'm extremely p*****, spent money and lots of time to hang.
