I used to carry them and they outsold the other ones I had. However, I was not impressed with the wattage 12-14 watts were the ones I had. Being the smaller wattage, they took much longer to melt the melts/tarts and sometimes the smaller wattage ones had a ring of unmelted wax around the outside edge. However, they work great for those who use very LOW mp wax or just f/o. Jackel products are very nice and I have nothing bad at all to say about their customer service. If you are wanting some of their products, give them a call and find out the higher wattage ones and order those to have on hand. I would make sure if you list the warmers on your site, be sure to list the wattage too. Good luck!!
