Product review (3 stars): Looked the same but...
These items arrived as advertised. However, they seem to absorb more water or just are heavier with the same amount. When they are placed on the normal float stand, they literally sink the stand to the bottom. There is only a couple inches of air space above the water line (when full) but the humidifier functions nonetheless.

Overall, they work but not as well as the originals. They were nowhere near the price though either.
