Great product and customer service.
I love the brush itself (have had it for 2-3 years), but was not happy when their confusing website led to my receiving the wrong color replacement brush heads. At first they refused to correct this so I posted a two star review (as NJSpice). I couldn't find a way to edit/update that so I'm doing so here because they reconsidered and ended up sending me the right color (& let me keep the wrong ones). I really appreciated that, and they have also been good about responding to a couple questions about the brush I've had over the years.
