Example Input: This coffee cup is just about the perfect size. I enjoy drinking an espresso and a large mug will not always fit. So while this product didn't solve my problem it came pretty close. The color of the chocolate brown adds to its classy look. It only gets 4 stars because you have to hold on tightly when washing or any liquid from your beverage will spill. A great buy though for anyone that wants better tasting coffee!
Example Output: Good Review

Example Input: Excellent product, easy to read without glasses, works on every type of battery and does not require any additional power source other than batteries. I use it with a small LED flashlight for all kinds of things including checking my golf swing. The LED is much stronger then the old flashlight. A plus is that I can clip this device anywhere in place which makes clipping or removing your shoes even easier. If you need a great reliable wireless device, get this.
