I was at a local fair a few weeks ago, and was placed beside a couple of Pink Zebra consultants. They were telling people that all they had to do is place a few of their beads in their warmer and it would last for 30 days! I have scented dots as part of my line too, but no way can I get a month out of the scent! The funny thing was, they had a couple of burners going. But people could smell my melts, candles and dots without a burner when walking toward my booth! I know I can get a lot more hours out of my scents in my room at school, but not nearly as long at home with all the traffic, and other smells such as cooking, washer, dryer, dishwasher all of those things throw a scent too! I think, the same as the posts above, it depends on the place the melts are being used. I also tell my customers there are a lot different factors that will effect how long their scent will last.
