I've never seen the DVD, but surely you would be beter off investing in some further training where you can get hands on with the tutor? I dont really think you can ever get out of a DVD what you can get out of being able to ask questions and be shown to a way that suits your waxing style IYKWIM.
For instance, Tonilee trained with Kim last week, now with Lee being a bit cack handed (no offence love! lol), Kim had to adapt the method around her to make it easier. If she had learned from a DVD she would not get this, she would have to stuggle to do it that way.
Yes a DVD you can go back to, but it cant answer your questions?! I would be bloomin amazed if it could! lol.
Further training would always win hands down for me.
Also this has been talked about many times before, if you do a search you will find what you are looking for!
