I bought these for my daughter's luggage. We were flying and I wanted her to be able to easily spot her luggage on the carousels at the airports. We didn't want to spend a lot in case the tags got lost. I am so pleased with this backpack/luggage/purse attached tag or toggle! The multi-visual depth of each lighting color is vibrant & beautiful. Charges through a provided USB cord & the charging time was quick! The time the charge hold seems to be lengthy too. The toggle is attached to her carry-on bag and I have attached the other tag to her personal bag she takes on the plane with her as her "under the seat" bag. These were a great purchase and I highly recommend them!
