Review on 🌈 Versatile 7 Pack - Jytrend 9ft Neon Light El Wire with Battery Pack in 7 Vibrant Colors by Efraine Cruise

They were very easy to use. Each color comes with its own battery. I used them to make signs for Halloween. They bent slightly and formed words for my signs. They were very bright and lasted all night with no problems. The only real problem I could see is that you can't string them back to back. However, each strand was long enough that I didn't have to worry about it. Batteries are quite heavy, so attaching a couple of them to something like a suit can be tricky. Batteries are not waterproof and must be protected when used outdoors. I've had great weather and only used them one night so I don't know how well they hold up over long periods or in the rain. There's a slight hum, but it's not very loud and doesn't bother me.
