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.
i wanted to love these so much!!! but they won't work properly... the first time i used them, it took a minute to get them to start working and once i got them working properly i loved the way it wrote.. but then every time i tried using them, it was the same thing i had to scribble and blow so much to get them to start writing and even then it wouldn't always write properly... and i try to use them a lot. still trying to make it work out. but i do how many of the pens actually work properly so far i've tried to make them all work and they all have given me a very difficult time. my in daily use pens are 6.. and they don't work well either!
