Was looking for a new toothbrush as my old Triumph 5000 just stopped worked. Saw that the Genius 8000 & 9000 no longer use NiCd/NiMh and use Lithium battery instead, so should have longer life than the previous ones.

A possible alternative is the genius 9000 with 15% on eBay is around $170 with almost the same features or the philips diamondclean which is $200+.
Don't forget 4% cashrewards.
