The boys and I have been using the Redragon mouse with our Asus ROG gaming laptops for years. This is the first time we've tried this wireless connection and it's really good. I wish they offered a wireless Mammoth model because that's the wired mouse I use and I really like the XL size, but it's still a fairly large mouse that feels good in my hand for a long time feels. Responsive well, no lags, no problems yet. Battery life is a bit fast, but I'm mostly speaking from my son's experience. Mine seems to run much longer but I don't really know how often it uses it, just when it disappears etc. I mean it should time out when the laptop is closed but you never know what might happen. It had way less battery life than what I'm used to from other wireless mice I've had. All in all a great wireless mouse, looks great, works great, adjusts well, etc. I see no reason to buy anything more expensive.
