Worked well on recent trip to Poland.
Style: Type E/F-Germany France
I stayed at 4 different hotels in Poland and there were no more than two outlets in each room. By using this, I was able to plug appliances and my phone and charger in at the same time. I thought the short cord might be a problem when using in the bathroom, but it was flexible enough to use there and on a desk.
