I bout retractable travel mouse and doesn't seem to work on my labtop

It may have a manufacturing defect. Have you tried it on another computer? If it works on another computer, see whether it works when connected to a different USB port on the laptop. If it does, then you may have a bad or damaged USB port on the laptop. If it works on another computer but still does not work on the laptop when connected through an alternate port, then see whether some other device will work when attached to the laptop's USB port. If neither the mouse nor the other device work when connected to a USB port, then you have a problem with the USB controller. If an alternate device does work when connected to the USB ports of the laptop, and if the mouse works when connected to another computer but does not work when connected to the laptop, then you have a software problem, and probably need to change the mouse driver in a control panel or setting in the operating system of your laptop.
