Logitech M510 vs Logitech M525

The Logitech M510 and the Logitech M525 are wireless mice with similar performance. The M510 has two side buttons and uses the newer Logitech software compatible with Windows and macOS. It's more comfortable and is well-suited to all grip types. However, those with extra-large hands may not be comfortable using a palm or claw grip, and it isn't suitable for small hands using a fingertip grip.  On the other hand, the M525 is a more portable option. It's well-suited for fingertip grip for all hand sizes except extra-large. Unfortunately, it uses older Logitech software, which is only compatible with Windows.
