After six months, I finally converted the little lady over to cartotanks! Man, you'd of thought I worked for IBtanked, lol. I've almost begged her to try a cartotank, but she was completely happy with her Protanks. Until this past weekend, we were in a B&M and she saw a pretty purple tank. It was a cheap tank but she wanted it, and it has worked good enough she just made me buy her a couple IBtanked tanks. She got some girlie colored caps/tubes, and I got to order two more for myself. She reminded me of myself after a couple days, totally impressed with the flavor and consistent performance. I'm sooo happy she switched, I'll get to add a new tank here and there, and she won't complain, lol.
