To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is not necessarily the fault of the seller... but be forewarned: the manufacturer does not stand behind their product. This is my 4th toothbrush from Fairwill, and the second to quit working. This failed after only a few months. I wrote to the support address and was given a long list of things to provide... which I provided. Thereafter, the so-called support people:
- ask for the same information again - eventually claim they will give you a gift card - ignore you (it's been a month since they claimed they would resolve this... and they don't even reply to emails)
So, between the product failing quite quickly and the time-wasting, frustrating support, it's not worth the purchase. It's a shame as it's a relatively well-intended product. It's just not made well, nor supported well.
