Is Eternity Aqua worth buying?

Yes if you want a fresh, easy everyday scent at a reasonable price per ounce. It is not a statement fragrance, so don't expect compliments from across the room.

How long does it last?

As an eau de toilette, expect roughly four to six hours on skin, less in heat. Spraying on clothing and moisturizing first helps it last longer.

How does it compare to the original Eternity for Men?

The original is a heavier, lavender-and-sandalwood scent with more warmth. Aqua is lighter and more citrusy, which makes it better for daytime and summer.

Is the 6.7 oz bottle a good deal?

Only if you will use it regularly, since fragrance degrades over years once opened. Compare the price per ounce with the 1.7 oz and 3.4 oz sizes before choosing.

Designer fragrances usually drop during holiday sales and department store events in November and December. Compare across stores rather than assuming one is always lowest.
