I saw an ad for this on TV the other night. Has anyone here heard of/used this?

Funny, I saw an ad for this the other day too. I do want to check it out and see how good it is

From a coworker who used to work there, he claims its "pretty sh*t"

But then he's fairly negative about his whole time there
