This Review Title is Dead watch, but holds oil scent well and the content is: I'd give it 5 stars, but the description states the battery should last 10 months, but died just a few hours after opening it and setting the time. I bought new batteries for it and it was still dead. I'm returning it, regretfully.<br /><br />The colorful sponges do hold the oil drops well. Lasts for hours..There are other information for this review, one is This reviewer did purchase it and the other is 1 people think this review is helpful.
