Dear Dell Customer Support,

I am writing to express my disappointment and frustration with the performance of the Dell MS116 1000Dpi USB Wired Optical Mouse that I purchased on [Date of Purchase]. Despite my initial expectations of a reliable and functional product, I have been experiencing significant issues with its functionality.

I would like to bring the following concerns to your attention:

1. Inconsistent Cursor Movement: The mouse cursor movement is erratic and often freezes or jumps across the screen, making it extremely difficult to navigate and perform tasks accurately.

2. Unresponsive Buttons: The left and right-click buttons frequently fail to register inputs, resulting in a lack of responsiveness and interruption to my workflow.

3. Poor Build Quality: I have noticed that the mouse's physical construction feels fragile, with loose buttons and an overall flimsy build that does not meet the expected durability standards.
