I have ordered from Scentsy for years. My warmer has lasted well over 6 years with one bulb. The wax melts are always good quality. I don't love every scent that I buy, but I have never had to deal with customer service. Their site says that wax melts can be returned for exchange if not used. I typically always use the melts before deciding I don't love the smell. I wish there was a place on their website to read scent reviews before buying. Also wish they offered free shipping with minimum purchases.
