This is my second wax warmer machine. I decided to try nova wax as my second one because the first one I owned and gave away after a move, was really slow in melting the wax beads I use. So I did some research and even though on Amazon nova wax warmer came listed later on their recommended list there were things I couldn’t ignore: made in USA, fast warmer/melting time, and they had a one year warranty if anything happened. I’ve used it so far one time and got my wax melted fully in half an hour, (which IS faster than my the other brand wax warmer I had) and the temperature control was easy to use and manage ! My only complaint if I had to find one is the box came without being taped. So when I received it, I was like what the heck? Did someone open it? But it came with a small dent on lid and didn’t seem like anything else was wrong, so I’m happy it works and works well !
