The software isn't that bad. I've had no stability issues or errors it all works fine. Granted, it's not the most intuitive of software but it's highly functional. The mouse itself is great! I've been using one for years. Today I'll be going down to buy my second one. Not because there is anything wrong with the first, but because I need one for my laptop. The mouse itself is comfortable, durable and highly functional. I don’t know how many MMO hours I’ve pumped into my one but I’ve not been kind to it and it almost looks new. The mechanical buttons show no sign of ware and have a really pleasant press. I saw the previous reviews and couldn’t leave the page with such a negative reflection on this product. I highly recommend this mouse.
