Sometimes needs to be "woken up"

Works ok - I find I have to wipe it on my palm periodically to get it to "wake up" sometimes. I try to use it and it is like it is not connected to the laptop - wipe it on my palm and suddenly it tracks on the screen. Update - while I consider the issue with the device to be slight annoyance, the seller has gone above and beyond to try and provide customer satisfaction. So for that they get a 4-star review.
