Bests & Worsts Reviews from Amazon

We have this mat. Our main problem with it is that it still emits a chemical smell after weeks of use. To test it yourself, put a large bowl upside down on the mat overnight so that no air can escape out. Remove it in the morning and immediately smell the inside of the bowl. You'll be surprised by the strength of the chemical smell (smells like gasoline). Whatever that chemical is, it keeps emitting into your house continuously. And if your child spends long periods of time on the mat, he/she is exposed to it the most. Until more tests are done, or healthystuff.org tests this product, I don't believe the manufacturer's claim of this mat being non-toxic. I plan to only use it occasionally outdoors in our balcony. PS: take the raving reviews here with a grain of salt. This product is manufactured in Korea, and guess what, many reviews on Amazon have Korean names (Disclaimer: I personally have nothing against Koreans -- I have lots of Korean friends). It also ships from Seattle, and voila, many reviews are from Seattle. Their page on the well-known social networking site is monitored so if you end up asking a question that they don't like, they immediately erase your question. If you examine the posted questions more carefully, they are mostly soft-ball ones from several users with Korean names.
