Both of my trusty Panasonic shavers, one foil, one straight trimmer type of, not sure, maybe 10 years? just died on me so this is a timely discussion for me. I guess that is the lifetime of the old NiMH or maybe even NiCd batteries... which is actually pretty dang impressive.
I also remembered another meaty thread on electric shavers from some time ago so searched and found:

Which has a lot of good suggestions.
FWIW, I am one of those pretty heavy beard but sensitive skin types plus am a proud bald guy, so have adapted over the many years to shave closely and safely.
For my facial and head shaving, the only way I can get a close enough shave is via traditional razor. And since I have decades of doing this, I have covered the gamut from the old Gillette safety razors, through Bics, to this and that and have the past 6 or so years settled on Harry's as my go to for shaving with some 3 blade disposables as back ups and for the boys. I get a couple weeks out of each Harry's blade and the shave is incredibly close, no nicks, no burn, very cool feeling for hours after.
If I need a quick touch up I have used my Panasonic foil (and I agree that foil needs changing) but for me, it just doesn't get close enough. I generally use my trimmer to keep my beard down to about 1/4" length.
For Big Jim and the Twins, I use it to keep things trimmed (its a wet/dry so can do this in the shower) but for the taint and the Twins, I use a disposable and have learned as have others that turning an electric loose down there is akin to shoving glass shards into your scrotum. Just don't!!
I also got another electric some years back which has a funky foldable handle letting me run it over my back once a month to get the two annoying hair patches under the shoulder blades but that is a sidebar topic.
Anyway that's my 2bits on shaving.
