I think these lights are very cute, and easy to put up! There are 16 icicles of lights in the 20 ft. strand. The icicles vary in length, to add visual interest, and contain 4, 5 or 6 lights in each icicle, with a Christmas tree at the bottom of each one.
I got them after Christmas, so I just I hung them by putting hooks up, and putting the wire over the hooks to get an idea of what they were like and how I might use them in the future. I tried the various program settings for the lights and I changed it periodically for a fun effect. The remote is identical to those that came with my other lights which is great, so I only need one remote to work all my lights.
My complaints are that you 1) need a charger to plug the lights into. There is no standard wall plug. 2) My lights came without instructions, other than those in very small print on the box, and 3) there was NO spare bulb included, though it says that there is one in the box. 4) It also warns on the box, that if a bulb is removed, the entire string will stop working. If the bulb burns out, but is left in place, it says the string will continue to work. I didn't test that. 5) The bulbs are not standard, either. So, I have no idea where you can buy bulbs like them when you need them.
I DO like them, but …… time will tell.
