I bought a set of Power Up Dumbbells from Mashable for my daughter as a Christmas gift. They arrived in a new, unopened box, but the dumbbells inside were missing a weight plate. It is clear that it was never packed in the box to begin with, as the styrofoam packaging shows only 4 plate indentations on the one side instead of 5 like all the others. I have tried to go back through both Mashable and Life Pro Fitness and both are totally worthless, two weeks later I am just getting the runaround and "we are looking into this" but no replacement yet. Life Pro says they can't provide a replacement weight and that I have to deal with Mashable on any returns or replacements. Mashable so far has done nothing to resolve this. It is very frustrating that two weeks after Christmas my daughter still does not have a useable set of weights and neither the merchant or the company that produces the product will do anything to help. I would be very wary of buying anything from this site.
