Would you buy a USB shaver? It sounds a good idea, particularly if you travel often, but check out some of the reviews first. They are mixed, to say the least.
Here are the headlines from four Amazon reviews for the Shavetech USB Rechargeable Travel Razor:
* Compact and useful
* Ordered two last month, but only one still works
* Great travel gadget
That pretty much sums it up.
Check out the Amazon website for more reviews and the latest price.
