Hi khp18,

'm sorry to hear about the issue with your Razer Viper Mini's scroll wheel moving in the wrong direction. Were there any incidents that happened to your device before the issue? Is there any noticeable physical damage from the mouse? Is the scroll wheel hard to turn or stuck in a certain way? Does the behavior happen while Razer Synapse 3.0 is closed or disabled? Please do the troubleshooting here. If the steps didn't help, PM with your device serial number and proof of purchase so I can check for replacement options. All the best!
