[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]: We are pad training on hardwood floors and tile. Other cleaners were driving me crazy, because they’ve disinfect but leave a sticky floor and sticky feet! This takes care of it all and no sticky feet. Just looks good as new afterward.
[EX A]: positive

[EX Q]: This item was great ... for three months, and then wouldn't work anymore. I'm trying to contact customer support, but cannot find their information. Does anyone know who to contact? It seems that a product like this should last more than three months.
[EX A]:
negative
