• Rechargeable
  Ergonomic Mouse: The Bluetooth Vertical Mouse has a built-in 500mAh
  Li-Ion battery that can be conveniently recharged using the included

• Ergonomic Vertical Design: The ergonomic mouse wireless keeps your wrist
  naturally straight, putting your forearm and wrist in a more natural and
  relaxed position, which can reduce overall fatigue compared to a
  standard mouse. Warm tips: We encourage you to relax your palm and hold
  the mouse naturally when using a vertical mouse

• Warm tips: Since it takes a learning curve to get used to the shape when
  using our ergonomic mouse for the first time, it may cause inconvenience
  to your mouse grip, We recommend that you take 1-2 weeks to get used to
  it, as many users find that it will help reduce the pressure and pain
  on your wrist caused by long-term use of the mouse and improve comfort

• Notes: We recommend that small to medium hands use our ergonomic vertical
  mouse. Please measure the size before ordering for a better fit and more
  comfort

• Adjustable Dpi & High Performance: 1000/1600/2400 DPI levels provide higher
  sensitivity than standard optical mice for precise optical tracking;
  with the back and forward buttons, you can easily navigate websites and
  increase work efficiency. Note: All buttons are not programmable and the
  forward and back buttons are not compatible with Mac OS systems

• Silent Clicking Sound: Our vertical mouse's whisper-quiet clicking helps you
  focus on what's important without any noise distractions. Therefore, it
  is perfect for shared workspaces such as offices or libraries
