I just started testing with Eco Advanced and I love love love this wax, IMO it has to be the prettiest soy wax I have ever seen. So far I have poured about 6 10oz jars and have had no wet spots, sink holes or craters, tops come out smooth as a babys butt and takes nicely to color. I just burned 2 of my jars within 24 hours of testing and I'm getting a great hot throw and great smooth top after burn. BTW I use NG, JS and Daystar scents and they all seem to be working very well. I think this wax may be my salvation in soy...I can't wait to try them in a week to see if they are even better... BTW...I have also had great luck with Enchanted-Lite Millenium blend...just not as pretty as the Eco and since I'm looking to sell I think first appearance is really important.
