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.
Useless product, cheaply made. Trust me, it will cut your SIM card into two places. It does not matter how careful you are. It is impossible to align. Complete waste of money. You might as well use a scissors. This bad product ruined two SIM cards for me. I ended up buying new SIM cards from my carrier, T-Mobile.
