[EX Q]: Being a contractor for 25 years I know how to calibrate a stud sensor... this is the biggest piece of junk I've ever bought!!! I wished I could get my money back!!!
[EX A]: negative

[EX Q]: It's a world most of us will never know, so why not believe? Plenty of American heroes, a great WWII yarn, and mankind is saved. The boy and the girl find each other.
[EX A]: positive

[EX Q]: Got this as a surprise gift for my husband, as he is a wonderful aspiring chef. He's already worked through a number of really lovely recipes (the pancakes and smash burgers stand out as utterly delicious) and I am quite enjoying being his taste tester. The scientific approach is impressive and quite appeals to husband's sensibilities. It's been a very worthwhile buy, and comes highly recommend
[EX A]:
positive
