It seems ok. Not an awful start, and the fact that Walmart carries it ensures that in any emergency, that there will be a few more people who have something with them.
I'd wonder about the sheeting, though. Certainly, plastic sheet has its value. But first of all, any nerve gas attack (as the ad text goes on at length about) would happen too quickly to protect someone. More importantly, any room well-enough sealed to protect against that threat would suffocate those inside.
Its value for patching broken windows following a major storm, or as the beginnings of shelter in an evacuation scenario are far more important.
I guess they're selling what people are looking to buy....
