Review (1/5): Try it right away.
Bought it and it arrived well before my polish did, so in the box it sat. My polish finally arrived and I was ready to use it this morning. Plugged it in and out doesn't power on. The power supply has power because the light comes on. However, the unit itself does no signs of life. Out of luck, return window closed last week. Not sure what I will try next. Very disappointed.
