220V to 110V Step Down Voltage Converter 50W Travel

I recently bought the 220v to 110v step down voltage converter for use during my vacation in Northern Ireland. The product is well made and is of high quality. There is a problem though as the two (2) pin round prong plug cannot fit in the conventional three (3) pin square socket outlet. For the item to be of any use I had to use another adaptor with a three pin square prong and then to plug the two pin to it.

Another word of caution though, is that some people simply buy universal adapators for use in Europe for USA 110v appliances. This practice is not recommended since in Europe the voltage is 220 and can cause damage plus a fire risk by plugging an adaptor without a STEP DOWN VOLTAGE CONVERTER.
