HI -
I just didn't get on with the PHD system at all. I have one of the original heaters, and the newer ones are better so I believe. With me I always found the first application was fine, although the tubes were so hot they were difficult to handle even with a paper or fibre strip.
Once the tube had been placed back in the heating chamber the wax never came out at the same consistency. For me personally - I felt the whole system to be over- hyped. My friend , totally disagrees with me and she loves it. and would'nt use anything else.
One of its key benefits is the hygiene aspect , but I have to say that I have gone back to my trusty pot and spatula.
You have obviously based your decision on your own research and may be you've already worked with it. I'm sure you'll be fine. there's alot of people on the site who love it.
Regards
