Tea candles work better.
I purchased a wickelss candle warmer from a scentsy vendor at a fair. It sounded great! I would never again need a tea candle and have to relight it every time it went out. I bought one for $30 and some cubes to go with it. I plugged it in and the scent was great. It actually lasted a while. However, when I went to change out the scents, I used on of my favorite ones that was a fraction of scentsy's wax melts cost, and it took forever to melt. When it finally did melt, it was mostly solid the whole time. You cannot use another brand wax in the scentsy warmers. That to me is worthless because then I am limited to the scents that scentsy offers. No go in my book!
