I just received this melter (and I'm very excited about it). I rated it 5 stars because I believe that if someone knows how to fix the minor issues that they will encounter, this will be life-altering. I've been using smaller melters for quite a while, and they took my business to a new level; this melter promises to go even further.
A couple of caveats: first, pay attention to the temperature. You cannot simply set this to 185 degrees and assume that you will be good. Setting it to 185 will bring you to near boiling temps (in my experience), which of course is terrible for wax. The answer is to pay attention to it, check the temperature of your wax, and expect to turn it waaaaaayyy lower than 185 to maintain that temperature.
Second, the output/spout on this is tough. It's a huge spout, and the wax does not come out in a "stream" (hard to describe); rather, it comes out in a spray (like when you hold your thumb on the hose?)--no matter how slowly you try to pour. My husband fixed this problem on Day 1 by attaching a more narrow brass fitting/fixture/whatever you call it. It narrowed the stream, and resulted in the perfect solution! I don't understand why the manufacturer doesn't take this extra step, given the obvious use of the product. It makes no sense to me. That said, it was a pretty simple fix (the spout is threaded on the inside, so the added piece just screwed right on). It's now perfect (assuming I don't forget about the heat and boil my wax...haha).
All in all, this is a solid and beautifully built piece of equipment. I hope that my experience helps the next person (because losing a case of wax because it reached the boiling point is not cool). Thanks for a great product, Candlescience!
