The following text is my opinion about this gadget Aircon, I'll write down the things I like and dislike about it.

Pros:

• the gadget is able to change your mood (by changing what do you feel, the temperature)
• simple to use (it has only 3 buttons)
• futuristic design
• the price is decent compared to a smartwatch

Cons:

• nothing

The idea of having such gadget is nice, not sure how well it works, having something this small on your wrist might or not be able to change your body temperature.
