Title: Best if used in the USA only
Review: In this day and age when almost all portable electronic products are universal power based, I regret to inform you that the Norelco Trimmers are mono voltage and cannot be operated outside the US. The unit can be charged only from (110v /120V). Neither the Philips nor the Amazon websites point this out to buyers.Since I travel outside of the US quite a bit, it is a big hassle to use this trimmer with a voltage converter. I wish Philips would seriously consider this issue and improve on the product, hence two star rating.
