Sold at Walmart and Sam's Club --?? Makes me skeptical.
I did a Google search, saw many many forums where folks are asking about it, did not see anyone posting who either had used it, or had (yet) asked their vet about it. Lots intend to ask their vet.
It is a new product; I would rather wait and see how others react to it.
I saw 1 person speculate that patents on meds expire and that is when generics come out on the market. But that person said s/he didn't know if this applied in this case.
Also found this 1 caution:

Be very careful...these Frontline imitations may use the same ingredients but the concentrations are not the same. Many pets have already become ill from these new imitation products and they haven't been out very long.
