I bought this unit there are now 2 weeks and I could tested once. It is very easy to use, the manual is well designed. The appliance heats up very quickly and everything is provided in the kit is perfect for first use! I use it for personal use but it is a professional quality device, same as my beautician, I melt only the peel wax for bikini and underarms. I am totally fascinated by this and thank you amazon for giving me this comes with almost two weeks in advance, what joy! I recommend this article.
