Negative Positive
Title: It got hot and melted.
Review: We noticed right away that the switch got very hot when we used it for the first time a few weeks ago. My husband just took it out and noticed that the switch part actually melted. To those commenting that it drains the battery, when you connect it to the adapter, there is a positive and negative, like a battery, so if you attach it wrong, it will drain instead of charge the battery.
Is the review positive or negative?
