I love the cute theme of these reindeer lights. I like the ability to have them plugged in or battery operated, and that there is a remote. I hate that these things consume the battery power very quickly! This causes the lights to be dim instead of bright. In the month and a half I have used them, I have changed the batteries three times! Other battery operated lights I have with them have lasted about 4 years before needing new batteries. I have not tried plugging them in since the place I have them is no where near an outlet or usb.I bought these as a gift, so I don't know how well they work, but be aware that these are TINY lights. They should really be sold as "mini-lights." Each snowman is about the size of a US quarter. Considering the price, I thought they'd be something I could hang around a window, but they're much too small for that.The lights are cute but much smaller than I expected. The main reason I bought these string lights is that I want to use USB power, not batteries. The USB port and cord provided does not power these lights, so I am returning them.Not only cure but easy to use, multiple ways to power, and multiple functions! Great gift or stocking stuffer.Everyone comments on how cute they are on my small tree.These come so tangled up that they can’t be undone to use them after 15 minutes of trying I gave and I’m returning them!!!If you have all the time in the world and nothing better to do! Then buy these.They are adorable but can’t get them untangled!
