Whitens Wonderfully...But, Umm, Dies So Fast, You Don't Need An Extra Warranty!
Reviewed in the United States on November 22, 2019
I loved this toothbrush, since it worked quickly and effectively to whiten my once yellowed teeth! I only used it once per day and got great whitening results. But it just died no me, in several months, despite my full charging of it! So I contacted the Square Trade extended warranty company, only to learn that, my dud died too fast to qualify for extended protection! Square Trade told me to contact the manufacturer; the manufacturer told me to send them video showing the problem (sarcastic laugh). And I instead, successfully argued with Amazon and the manufacturer, that I deserved a full refund!
