Example Input: This product is great for adding a very pleasant color to your home. I love using the product. It does smell like lavendar but so does lavender. So far it's been great. The diffuser lasted two weeks with regular use. I'm happy and you will be too. Thank you.
Example Output: Good Review

Example Input: The unit shipped promptly with all the components. It worked well, for 4 weeks. After that point it would either not recognize CDRWs, or stop at the end of a disk instead of continuing to play. That was really annoying. I called Philips, who sent out 2 replacement DVDplayers which lasted longer than that. These came through after they failed in less time and did as they were advertised to, but only played half CDs when tested on another DVD player, so you had to listen using headphones.
Example Output: Bad review

Example Input: I should of sent it back but never got around to it. Don't waste your money on the product. Mine would only work for a little while and then you were just lucky if it would work. Very cheaply made. No idea why this was not in its original packaging. Never worked properly even though they claimed brand new. This is definitely junk!! Save yourself some grief buy elsewhere.
Example Output:
Bad review
