Review on 🖱️ Enhance Productivity with MOJO Silent Bluetooth Vertical Mouse - Wireless Ergonomic Mouse with Adjustable Sensitivity (Bluetooth Only) by Mary Beauchene

I don't know if this mouse has a design or workmanship defect, but it just didn't work for me. Once I plugged it in, moving it around caused the pointer to jump around all over the place, randomly changing window focus, and making windows scroll randomly. I thought it might be an issue with the DPI setting, but hitting the DPI switch had no effect - the crazy behavior persisted. Tried unplugging and plugging the receiver back in, but it still behaves like crazy. To be honest, I've tried powering it from the USB port on the KVM switch, but if that doesn't work, I can't use it. This is the second vertical mouse to fail in this configuration. I don't get it, any standard optical mouse will work, just not a vertical one. <sigh>
