I put my copperhead on the iMac and it’s like night and day, it’s that amazing. The copperhead feels like a BMW compared to the Lachesis which is more like a PT Cruiser and the prices should be swapped. The copperhead is a way better mouse IMO. It feels better not just in using the computer but also in games.
I’m left-handed so Razer’s mice are really great for me. If i was right-handed, though, i would have to pick between using the copperhead or the logitech G5. They’re both absolutely the best.
