Document: Single sided is enough and you can see them from all sides, Trust me. Finally something affordable for retailer/ fast food working class like me. I wanted to leave a comment and rating ASAP to help anyone else out this holiday in choosing these beautiful lights.
seeing youtube videos of these new snowfall lights looking so beautiful on trees i wanted some for myself instantly. Unfortunately I found out they were mostly $100+ for a bundle of 8-12 lights. That was a year ago because this year i found them for $25 so cheap for 8 of them and they are beautiful. I wanted these for one reason, to show off and boy are they good at doing just that.
You can go pay $50 and up almost everywhere but I gave these a try and love them. I still don't know how they sell them so inexpensive.!!! !
Very disappointed. This item took almost a month to come in, and when it did I went straight to plug it in, and it just didn't work. This is the first thing Ive ordered through amazon that just flat out didn't work. The price seemed really good compared to other similar lights, but I guess you get what you pay for.
Unfortunately they arrived AFTER Christmas, so they will be on display for 2014 Christmas. Excellent, pleasing lighting. Makes everyone smile
This is the third set of these type lights I've bought. I'm a sucker for brighty lighty things and these are so different. The color is fantastic and will look great in the tree in the front yard next Christmas. They use a regular plug and the very best thing is the price which is amazing. I'm buying more.
These lights are heavenly. They arrived fast & all of my neighbors love them. Look forward to purchasing more in the future. Can;t have too many of these!
These are amazing. They look blue though, not purple. I put them on my tree and hung some outside. They are incredible for the money. Everyone was asking where I got them. Best purchase ever! I'm getting more for next year!
I really enjoy these lights so far. When first turned on they all move at the same time, but as they warm up there is a slight variation of movement. They look really cool when combined with other lights on a Christmas tree.
Great product an an even better price, I can't wait to hang them and show them off to the neighbors.
