Didn't work, we tried using it for a solar science project with a 3V motor that was left in the sun for hours but it never worked . Update 4/3/19 about the item being returned and replaced and that they have confirmed that they received it on the 15th March. I'm still waiting for a refund. It's not much, I don't understand why they can't return it. π€·π½ββοΈ Attention buyers!
