Example Input: Bought this for a 2017 Ford F-350. Terrible product. Followed instructions exactly. Vent shades do not sit correctly so that when you put your window up it keeps going back down. Returned them and the company Auto Truck Toys only refunded 50% for a restocking fee. Product doesnt work but you have to pay for the terrible design. DO NOT BUY THIS PRODUCT OR FROM THIS COMPANY. You would be just giving away your money. I give this product and company NO STARS. I had give it a star otherwise it wouldn't allow me to submit
Example Output: negative

Example Input: This little diffuser charges with a USB cable and last about 4-5 hours on a full charge. I use it at my workstation and get many compliments on the scents I diffuse and the look of this little gadget. It is a great little diffuser!
Example Output:
positive
