ALUNME 40 Pack LED Light Up White Balloons Non-Flashing White Lights Party Wedding Balloons with 2 Sliver& Glod Ribbon Long Standby Time for Dark Party,Wedding,Birthday

Got these for our wedding and was incredibly disappointed that the ones that ended up working (about half) didn't last long at all!

I read all of the reviews and saw the complaints about not lasting long and did not work as they expected. Months before we plan to use them at a night wedding I decided to try them. I blew one of the white and one colored up with air and put them in the closet. The color changing one lasted almost 24 hours. I can understand this with all the changing it was doing. The white one was lit at 5 pm on Monday. It was still working when I left for work today at 5:00 am Friday. Read the directions and they work perfectly. Will update with photo after the big day.
