I use an electric razor, and will continue to do so for some time to come. I think they're great, and the reason I switched from manual shaving to electric is because I didn't think I was getting a close enough shave (For the amount of irritation that occured) with the "Mach 3".
I have a Braun "Syncro" and have been using it everyday for a couple years now and I think it gives me an incredibly close shave with very little irritation. (I'm only 21, my beard isn't growing to its full potential yet). I've only replaced the actual blades once, and it still works perfectly.
I personally recommend trying it out (Though it could be a costly mistake). I'm sure as hell glad I did.
