[EX Q]: Well, I've given it 6 weeks, using faithfully morning and night. I was hoping for longer lashes (but I wouldn't have given a one-star review if I had at least gotten fuller). I haven't noticed any change. To top it off, the last 2 weeks I have been babying my tube, since it developed a crack/leak along the bottom edge.
[EX A]: negative

[EX Q]: These are postcard stamps that the seller takes forever (pun intended) to mail. It was amazing though ... Once I tried to cancel for taking too long they shipped that day. Soooo incredibly irritated with this purchase.
[EX A]: negative

[EX Q]: I don't understand how people are giving this five and four stars. It has to be the most discussing instant potato mix that I have ever made. I do use the other varieties of potato mixes - and enjoy the flavor - but not with this. Like another reviewer asked, what am I going to do with the other six packages. I will be buying real sweet potatoes during the growing season and freezing them.
[EX A]:
negative
