For years I've been a Braun user. Then I discovered the linear motor shavers from Panasonic and have been using one for the past 10 years.
Five years ago I saw another Panasonic linear motor shaver in Singapore airport and bought it. It is my favourite shaver now. It is also a linear motor shaver, has three cutting blades and a very good trimmer. Charger works on worldwide voltage. The shaver uses a Li-Ion battery inside and one charge goes for 14 days. So for travels shorter than 2 weeks, no need to carry a charger. Shaves very close without irritation or pulling hair and it is reasonably quiet. This is a very compact machine and it is perfect for travel as well.
