The product is fine, same as shown on facebook post. I took a gamble and bought two even though I hadn't smelled the fragrances. When I received them, the instructions were very confusing. All I actually had to do was push up the tube then screw the fragrance bottle in. The freesia and pear, and apple and cinnamon, fragrances are spot on. The unit is very easy to operate, only a couple of buttons to press. It is quiet and doesn't require any water topping up. I haven't tried the other fragrances yet and feel if samples of the fragrance had been sent I would propbably have bought some extra to keep in stock. I bought these half price and that is worth they're worth, the units are fairly basic and wouldn't justify paying more - I paid for the convenience of not having to keep them topped up and the ease of use. I might purchase more sets in future.
