PROBLEM: Used it a couple of times over the course of a month, and it worked great! Third time, high pitched noise, and no mic signal coming through. Not too surprising, given how flimsy this thing feels. This is apparently a known issue, just look at other 1-star reviews of this product. 'Nuff said! 
 Polarity: Negative

SOLUTION: True

PROBLEM: Love PG Tips tea.  It's hard to find in the USA, but a standard in the UK. 
 Polarity: Negative

SOLUTION: False

PROBLEM: I have bought Duncan Hines Yellow cake mix in the past and have made a favorite recipe with it.  In the past, it had 18.25 ounces.  Pillsbury and Betty Crocker have the required ounces 18+.  I bought Duncan Hines at Safeway because it was less expensive than the other brands and after I got home, I discovered why.  I will not buy Duncan Hines again unless they go back to the 18+ ounces or go to 9 ounces for $.54.  Consumer beware and read the number of ounces in the product. 
 Polarity: Negative

SOLUTION:
True
