Poorly Written Instructions
This came with no clear instructions - as a result, I was very reluctant to use it given the danger of burning myself. The instructions were in very small print and there was a chart showing the different levels of heat that you should use depending upon the color of your skin - light, medium, dark. This felt weirdly racist for some reason, perhaps because the writing was so poor. For something that affects your skin I would only use a device like this if the instructions are clearly spelled out.
