KAWAMOUSE2.4G Ergonomic Portable USB Wireless Mouse for PC, Laptop, Computer, Notebook with Nano Receiver (Floral Yellow Sunflowers)

Not sure I would consider 5his mouse ergonomicly correct. I do like the colour scheme.

I received this mouse on October 26 and started using it the next day. Today is November 10 and it is already not working. Up until yesterday it was fine, yesterday I tried to use it and it was not connecting to my chrome book. I flipped it over and saw that when I first turned it on the red sensor light would turn on for about 2 seconds and then turn off and remain off. I replaced the batteries twice with brand-new ones but the same result.
