I trim my pubes with a basic battery operating beard trimmer, I use a fairly short guard on it. But I actually shave my balls, personally use a Gillette Fusion razor. The trim part is super easy, just run it over. The ball shaving, it is best to do it after or in the shower, that way your sack is loose and isn't tall tight, when warm and wet, you can stretch it easily, I do it without shave cream after the first time, just maintenance as long as you have plenty of water.
