Sitting in the breeze way between the garage and the house in the summer gets flys and mosquitoes,this zapper does the job to get rid of the little pests.The fan is quiet and works great do draw them into the device.We had a zapper light but didn't work as well as this one.However this is not cordless and needs to be connected to a power adapter such as the small usb power supply.It comes with the new "C" connecter cable and small brush to clean out the catch tray.
