longest lasting cartridge?

[hyperdeficit]

Hey all,

cartridges are expensive, some sites say you should change them every two days. others say after five fillups.

This can be pricey considering a single cartridge is about $.90 to $1.30

I have been doing a little experimenting with two cartridges, the first one I went a week ( 25 mls vaped that week) and had no problems, the filler wasnt even brown.

the current one i have been using since last friday and the filler has gotten a yellow hue to it.

whats the longest anybody has used a single cartridge?

on a side note, I saw a link for do it yourself carts involving hypoallergenic pillow stuffing. I lost the link can somebody send it to me?

Thanks

I use Lypton Pyramid T Bag filler and wash out every 2 days, been using 1 for about 10 days now- still perfect
