Hey there, here is a major throw back topic.
I purchased a mouse back in the promo, immediately lost it and just came across it again. I contacted razer to ensure it still works for the crystal. They gave me a code since I didn't ever activate it, and at this point I'm trying to figure out how to actually get the crystals.
I have Razer Synapse 2.0, a code, and no idea how to combine the two lol. Any ideas?
