Review (1/5): 1 used to last 6 months; now 2 in 6 weeks.
I don't know if it's the old ones that are getting sold on Amazon or what but I've gone through TWO in less than 6 weeks! I used to live this product but now, NOT AT ALL. I only thought to check if it was returnable today (because I thought the first one was a fluke) and naturally, it's only refundable for 30 days. I'll never but this item again from Amazon!
