Bests & Worsts Reviews from Amazon

First, let me clear up some misperceptions that I see being posted here: Smart phones, tablets, laptops, and even battery chargers for digital cameras do not require a voltage converter. All you need is an adapter to plug into a foreign outlet (and it's becoming pretty common for hotels and airports to have universal outlets). There are few electronic devices that you are likely to travel with that require a voltage converter — and some like a hair drier should not be used with the BESTEK converter. What I use the converter for is my electric toothbrush which will not work with 220-240. There are universal charging bases, but I was having a hard time ordering one so I just went with this. I've used the BESTEK on multi-week trips all over the world to keep my toothbrush charged. Never had any problems.
