Most everything I own is pyrex, at least up until the last couple of months. I sampled one each of most of the last generation clearomizers for my daughter's first mod setup before settling on the iClear 30's as my favorite.
I've always been an advocate of pyrex. I have been and still am critical of manufacturers that insist on still using polycarbonate materials that house e-liquids. I recall not trying a Vivi Nova for the longest time solely because it was made of polycarbonate. I did try Smoktech's polypropylene version - the Screw Tank, aply named by Smoktech. But then again it was made by Smoktech.
This only contributed to my opinion of their products.
The fact that the manufacturers were wrong in believing customers would not pay more for pyrex is telling. The manufacturer who was willing to listen to their customers who lined their pockets with money and was willing to be innovative is getting their payback now. Way to go Kanger!
Now the competition can't wait to add a pyrex version in their line of products.
