Ha! echt yes, similar here, only i thought it was a light-hearted thread that 'manual' toothbrushes should last longer than five years, and i thought it was hilarious, and yes, how absolutely awful that they dont do a lifetime toothbrush.
But...i use my hand, saves electrix. That comment could go for other battery operated devices mentioned above too 
Good to see lovehoney being responsible and useful to know.
I also want to go back to hand mowers, very well.designed ones, and that way i get exercise whilst mowing, a good workout and save the planet into the deal too.
Ive personally given up with the electric t.brushes, and have excellent health hygiene comments from dentist about healthy gums etc, but have [last christmas] bought the fairy ones advertised by MN for christmas presents for my teens, as oral hygiene incentives, and so far only needed a couple of recharges (six months in) - and they are being regularly used!
I used to buy the higher end ones, and wouldnt waste my money now.
