BORND C170B IRON GRAY / Bornd C170B Bluetooth 3.0 Wireless Optical Mouse (Iron Gray)

I am finally done trying to get one of these to work consistently. I have three and often have trouble getting any of them to work. I take the battery out of two and pair the remaining one and sometimes they work well.Sometimes. Do you know what works consistently for $9.99? https://www.amazon.com/VicTsing/b/ref=bl_dp_s_web_6920851011?ie=UTF8&node=6920851011&field-lbr_brands_browse-bin=VicTsing
