This is definitely a good hunt! @kimsungmin thanks for sharing it. Here's what I can say about this hunt.

Pros:

• It can help the people have more better and decent sleep with the help of the mask and also the music that it will play.
• People will be able to track their sleeping pattern such as snoring, dreaming etc.
• It is lightweight and as per the design it is just like the basic eye mask for me.
  Cons:
• None for this hunt as it helps people to have a better sleep. Price wise it is still okay for me.
