I used double head safety razors in my youth and after being dissatisfied with several electric razors I decided to go back.
One word of advice, DO NOT buy any of them till you've held one in your hand.
Because of my youthful experience I bought a Wilkinson, thinking that it would have had the same balance as my old ones, what a disappointment!
It is head heavy, not what you want, you want a razor where the weight is in the handle, that way you can be gentle with the head and it's easy to handle
also don't buy cheap blades, those scrape and do not cut.
