Had in the past year ordered several products and received all promptly with no difficulty regardless of what warehouse sent them. As to whether the products "work" depends on the product. Most supplements are a waste of $$ regardless of who sells them. The water filters are fine but manufacturers are deceptive when they tout the ability to filter out viruses. If viruses are contained within living cells that may be found in dirty water, then the filter will capture them, as procaryotic and eucaryotic cells are large. However, if virus particles are free-floating in water, the pore size of filters are not small enough to capture those particles.
