I started making tarts in April.. been testing ever since. EcoSoya PB is the wax I originally chose after doing some research and I've been using it since. Only lately, I've decided to branch out and test other waxes. In my opinion, it only makes mediocre tarts. That's just my opinion and with my experience. It just doesn't work that well for me. Cold throw is nice.. really nice. Hot throw is blah. Not long lasting and usually not even strong to begin with. I've tested it with over 100 different fragrance oils and only had ONE batch that threw like a champ. That one fragrance oil made tarts that lasted for 2+ days. Like I said, it's only my opinion. I don't want to offend anyone who uses this as their primary wax.
