Loved these twinkle lights all 6 times they worked! Total time on was maybe 3 hours before they would no longer turn on. The times I used them, I turned them on while I read on my kindle in bed for ambient lighting. I normally only read for 20-30 minutes. I haven’t tried replacing batteries yet, but they should definitely last longer than they did. It’s also strange that none of the strands will turn on even a little which to me means there’s a problem with the lights and not just dead…

I used them less than 5 hours and batteries are dead :( I was so excited after all the time I spent arranging them around my place.

First Revain delivery continues to be not only great but stunning sometimes in how quickly things come. This product operated just as expected and with no issues. Great value as well.

The brightness is good and they look mice but died after few hours of use. Now the remote also does not work. That's my review!
