Title: The ONLY oil I put in my sports car! Review: Royal Purple has been great for as long as I have used it...several years. It makes the car run smoother and since the engine is doing the work easier due to less friction, it has increased the miles-per-gallon as well as adding a few HP, too. I have a turbo-charged, all-wheel-drive, premium fuel-burning sports car and I demand ONLY the best for it. Like thousands of other auto enthusiasts and tuners, Royal Purple will contune to be my choice. Does this product review convey a negative or positive sentiment?

Title: I wasted my money on this one. Review: This phone lasted about two and a half months before the caller ID function failed. The retailer would not take it back, and, after four calls totaling about two hours of being on hold and speaking to "customer service," I first got the advice that I should attach another caller ID phone to the outlet or take my phone to someone else in my area code who has caller ID and ask that person to permit me to hook up my phone to see if the display worked. The best part of this advice is that I found a better phone at the same price. Assured that my caller ID function worked, I called "customer service" again and discovered that they wanted me to package the phone, ship it back to them, and wait six to eight weeks for a replacement. I do not recommend this phone, and I regret that AT&T has licensed its name to the company that manufactured this "product." Does this product review convey a negative or positive sentiment?
