To calculate the overall star rating and percentage breakdown by star, we don’t 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.
The actual product was fine. Shipping speed was OK. The problem with this purchase is that I thought when I purchased it it also have included registration with the site and it was ONLY AFTER I received the product that and tried to register the chip that I found out you have to pay an additional $25.00 ! This should have been advertised in the listing for this item !!
