Good shave, lousy batteries

I've had this for a week now. I have a very heavy beard that goes in all directions. This unit is at the bottom of their Coolskin line and uses their older shaving head technology, by the way (all slots vs their new technology which uses a combination of slots + holes). I use it with shaving foam, not their expensive Nivea packets. I get a very close shave, though it's difficult to shave under my nose and under my chin. The unit feels cheap and uses NiCad batteries -- this is the biggest problem I have with it. NiCads suffer from memory effect unless you frequently let it run down all the way (and as you can't run this corded that presents a problem!). On other products that use NiCads the charging unit itself will dishcarge the batter first eliminating the memory effect, but not this. Also, the charger will not prevent overcharging -- you can't leave it in the charger more than 8 hours! In my view these are fatal flaws. I'm sending it back
