[EX Q]: I am so excited to get this sweat vest! Fits great zips up easily. Fits and stays a lot better then a normal sweat band or waist trimmer. The smell of the material goes away as soon as you soak it in water with soap. But all and all great product.
[EX A]: positive

[EX Q]: I ordered from Amazon because the only 5oz cups locally seem to be child oriented and not for an adult bathroom. Ha! My dixie cups have riddles on them and are as cartoonish as the ones I could have bought down the street. I'm throwing them out and getting a hard plastic cup. So mean to send something other than was pictured!!!
[EX A]: negative

[EX Q]: Don't waste your money. This thing is wildly inaccurate, even after following their poorly written instructions to calibrate it I could never get a consistent reading. Not even their own buffering powder could get the same reading twice
[EX A]:
negative
