Query: WOW!

I'm looking at 140 people who bought and reviewed this item, while instead of buying 2 refills for $4 they could have purchased 12 "whole" G2 pens for $18. Think about that. I payed $1.50 for my refills, but I had to go to the extra effort to unscrew and discard the actual pen that came with these refills to then fit the refills into pens I may have just discarded in the first place.
