Bests & Worsts Reviews from Amazon

I cannot comment on product...After reading the directions, I discovered this has to be used in a well ventilated area and is flammable. Why aren't those two very important facts clearly visible in the description of the product. I live in a small apartment in a senior community and decided not to use it. I can't believe Amazon sends products like this thru the mail. Every package I mail at the post office, I am asked if there is anything flammable in the package.....
