Worth buying a 100$ gaming keyboard?

Solution
Well, it depends on what games you are playing? Do you use your keyboard a lot? Are you competitive? Do you care about comestics?

I have the Corsair K70 and it suits me perfectly.
Test it out man. That's probably the only way of getting to know if it's worth or not. Give it a full test(you already bought it right):
1. Play all of your games with it for about an hour each
2. do a type test - keyhero:

3. maybe invite your friends and let them test it and tell how the feel about it
 


 


And that is probably what is best for you. You can return it, and if you are not competitive, then get a more simpler keyboard.
