Jeez, I was so dissapointed when unwrapping 7 rolls for EI testing.. I had two out of the 7 that came out of the package rolled loosely so were exposed to light.. I tossed em. Anyone experience this problem? I figure if this is common, I might as well spend the extra money to get the branded ones. The way they are taped down isn't even straight so I have to make my own crease so it'll hold on to the spool.. gah..
