Air Monster 7-Inch 2-Speed Personal Box Fan in Black

I bought this fan to take on a trip. It is lightweight and works great.

I sleep with a fan on at night for the noise. This fan started out great but soon started a rattle that even a fan lover like me can't sleep well with. I purchased another one in hopes of getting a good one and having it last a lot longer before a major rattle started. Wrong this rattle started even quicker. I bought a vornado and currently it is working awesome.
