I bought this decoration, thinking of decorating the tables of my restaurant for Christmas, I did the first test and the batteries lasted 20 hours, today I put a new set again to measure time again, if they are not what I expect I will discard the purchase. Calculate there are 90 tables = 360 batteries changing them every 24 hours does not make sense, they guarantee more time of life but it is not like that.I will send my second report.The lights brighten my window and add a fun, whimsical aesthetic at night! I also hung some outside on a tree for the holidays; no need for an extension cord because these are battery-powered. Keep in mind you’ll need to change the batteries depending on use. They take 4 AA batteries each.Good lights and features. Look 100% better in a dark place. They are on the small side so look at the specifications before purchase. Remote easy to use and can send signal from far away.These lights stand up to the outdoor elements and add a fun bit of outdoor ambience during the dreary winter months. A nice selection of colors is offered, though I chose the white for versatility. I put mine in the outdoor planters flanking my garage. The timer feature is great, as are the variety of settings. They aren't quite as bright as I would've liked due to the delicate size of each wire/bulb. The remote took a bit of trial and error as two come with the lights, yet you can control both from a single remote. Overall I am pleased with this product.These are so cool. You can manually shape them into any shape or size you want. They look better in person than pictures show. Only issue I had was 1 out of my 4 just completely stopped working after a few days. All others are fine.These lights works great and looks good. Batteries last pretty good and remote works goodLove these lights, the color and sparkle effect are so pretty. Based on some of the reviews I thought I was going to use tons of batteries on these, but they lasted 2+ months with one set of batteries in each! I hung them on my porch for the holidays and haven't wanted to take them down. They sent a remote with each light, but you only need to use one remote for all of them (I have four). If you set the timer, they will come on at evening and go off 4-6 hours later. I had to reset the timer a few nights in a row, but once it worked it kept on working on it's own (no idea how this works but it does!).Love these lights, especially the timer function, but goes through batteries quickly. I have now purchased rechargeable batteries. I got the lights as part of our holiday decorations but have since kept them hanging in our backyard and they create a lovely nighttime tableau.Leider waren nur 3 grün und eine weiß!
