Philips Oneblade works really well for me on my whole body, and it's really not a hassle to use. I use it directly on dry skin and I get pretty smooth. I can use it on my face too, but it is a little harsh so I prefer a foil shaver on my face.

Charge lasts a while, you can use it in the shower although it's annoying to use on wet skin/hair. Replacement blades are not obscenely expensive, they last at least a month before I switch them.

I've been using the same one for years, only had to replace the blades.
