This seems to be a good deal for an Oral-B electric toothbrush with Bluetooth. Do not know how it compares with the Triumph or Genius Series 8000/9000.
RRP indicated as $269. Did a quick google and it is selling at $159 elsewhere.
For free delivery over $100, perhaps add one of the Lif3 SmartChip for $2 as per this OzBargain deal: https://www.ozbargain.com.au/node/441473
Seems like a good price for a toothbrush with lithium ion battery.
