Review on Sculpt Comfort Mouse H3S-00003: Win7/8 Bluetooth, HDWR Black for EN/XC/XX AMER Users by Nadia Miller

Works great until it stops. This is the second one I've had and both had the same issue. The mouse works beautifully and then suddenly goes dumb and doesn't respond smoothly to movement. Sometimes the cursor just stays put. I need to have my wired USB mouse ready to continue working. Try using an MS mouse later and you'll be fine until it starts behaving again! I have had several wireless MS mice in the past and have always liked them. I've had the last one for several years, which is a good lifespan considering how often I use it. Unfortunately this model was discontinued so I bought Sculpt. Not happy and I would have sent it back but the return period has passed (as I've tried many things to get it working). I went back to a cheap or free Dell wired mouse and it works great.
