I was nervous about buying it based on some previous negative reviews but it worked very well for us during a recent 3 week tour of Africa where there was a lot of emphasis on diversity out of 240 -Volt sockets. Batteries for cameras, phones and iPads. No problem and I suspect some of those negative reviewers didn't heed the warning not to use them with devices like hair dryers etc which could draw too much current and short out the converter.
