My wife loves this brand and style. Ive used these with Vidyo, WebEx, Skype, and GlobalMeet so far. Using without a computer will kill your battery life probably in an hour when playing a game like that. I have 4 other Adidas slides, those are great, the best. I would keep and use these lights. I read a lot of reviews were people said you can?t charge it with a case on, however I found that to not to be accurate. To be honest it still can have a tendency to slide but less so. They work perfectly with my Festool, and I get two rails and connector, for the price of one Festool rail of the same length. Nothing compares to the ease of installation. Pero una excelente compra.
