Been hearing great things about this toothbrush.

The wife's soocas x3 died after about 2 years went flat never to be able to recharge.
Cheapest price posted it would seem. Don't forget cashback.
I got a $2 voucher when I logged in, then used the coupon code and turned off insurance.
OP, is the shaft on this one plastic or metal? Picked up an ultrasonic for the kids from Aldi a few weeks back, and the vibrations and noticeably not as strong as my Philips Sonicare, I believe due to the shaft being plastic and as a result not transferring vibration to the head as well.
Also, where do you get your replacement heads from?
