Mouse between 40€-70€ for FPS Right Hand Claw

[SharpShooterPOR]

So I need a new mouse and I'm willing to spend up to 70€. I usually play Rainbow Six Siege (FPS) and I hold my mouse in  a claw style with the right hand. I've done some research and I've come up with some options:

 

Steelseries Rival 100 - 40€ w/mousepad

Steelseries Kinzu v3 - 40€

Cougar Gaming Mouse 300M - 46€ is this brand even known

Corsair Gaming Sabre Optical RGB - 56€

Asus Strix Claw - 59€

Steelseries Rival 300 - 70€ w/mousepad

 

So I also would like to be able to change my dpi to whatever value I want, I know you can do that with the rival 300 but not with the rival 100, but I don't know about the rest of the mices. I also need a mousepad so consider that I'm going to have to spend at least 10 more euros if I don't buy a Rival mouse. What do you guys think, is it worth it to spend 70€ and get a RIval 300 or is a Cougar mouse enough. I'm not a pro gamer or any thing of that kin but I like to be competitive and I need a mouse seeing that I use a mouse that came in a bundle and it's shit.

 

Thanks in advance guys

Rival 300 is a good mouse.

I think logitech G502 is a good bet, Rival 100 and 300 are decent too. Maybe go to HardwareCanucks and look at some of their vids
