Title: Not what I expected
Product review: I usually buy the O2 Spa, which is usually on Delta transatlantic flights. This time I thought I'd order this - how could it be so different? Sadly it is. It's like VERY salty water which has a nasty after taste. And unlike the O2 Spa I don't feel anything. The O2 Spa does in fact give you a boost. This does nothing.
Would you say this review depicts the product in a flattering or unflattering light?
