Purchased 22 sets of 2. We used these for outdoor lighting for a party.Pros:Very pretty, assuming you like one of the lighting effects.Fairly durable, based on our frustrated, rough handling.They have a pretty good battery life. We left a strand on for days to see how long it would last, and it was 5 days before they started to fade. That is continuous on, not using the timer function.ConsThese are a beyotch to unwind and separate the strands. I had two people working in tandem, one to untangle and one to place. The untangling took a minimum of 5-10 minutes per strand. Plan accordingly.There is no firefly effect (random single bulbs going off here and there), despite the product title.There were some quality control issues. Some strands just did not light, and others had been assembled at the factory incorrectly. In all, out of the 22, I returned 6. Included in the six returned were 2 strands that were white, not warm white. Thus, do not order the minimum for your lighting needs, and test them as they arrive.I wanted to add some magic to my standing shower at home, and these did just the trick! They are completely waterproof, I've had no issues. I've had them up for a few weeks now, and the batteries are still going strong with almost daily use. There are really bright, but can dim down. It did come with a remote per unit, but one remote does work for both lights. I used command hooks to hold up the lights.So far so good. Product seems to be everything it was said to be. The remote control is handy except if you put the lights inside of something like a watering can you have to get real close in point inward to get it to remotely turn on and off but once you set them you really don’t have to touch them again if you add the timer function.So far I’m happy with my purchase but I’ve only had them in use for a couple days. I do believe the remote control would work a lot better if it wasn’t inside of whatever the lights spill out of.Unfortunately, the products is not like it was pictured. It’s shorter, thinner and gets tangled a lot. In order to have it looked like on the picture, you’l need to purchase at least 10 of them!I like these but one wasn't working, never heard back from supplierThese lights are very versatile because they are battery operated so you can use them any where even outside because they are water proof. I love them. The 8 functions are awesome and the remote is a plus. I will probably be ordering more.Too expensive if they do not work! I would stay away from them as they did not give me the effect because the strands are all clumped together and then after all the work of hanging them on my porch they no longer work after only two weeks! Daylight robbery!
