Gaming Mouse 2019

Any suggestions for me to buy a new gaming mouse? thanks in advance!

Roccat Kova using it since 2 years and it feels like new

Depends on the use.
that duration or comfort

For me, I use a CombatWings,
Models: W200
DPI: 6000
quite good battery life.

I am going to buy a Logitech G502 is a great mouse tbh, a friend bought it and I have been looking forward to it since then.

Logitech mouses is good! If you need wireless mouse, Logitech G903 is good choice!

If you need a cheap (and small) Logitech mouse I have the Logitech G305 Wireless and it's shockingly good for an under $50 (USD) mouse.
