Traction device for post op recovery

[sky43diver]

Dear all,
I am 4 weeks post op Lue procedure (incision and grafting) and so far the healing process is going very well. I now have a completely straight penis. As part of my recovery program I am doing light stretching/massage, along with light VED and whilst I notice that I am getting back to pre op length I have noticed some shortening.
I have read a lot about using traction as part of the recovery strategy and was wondering how effective this is. I have spoken to the Medisure rep in the UK about the Penismaster Pro and he advised that with compliant use I could gain back over an extra inch.
Is this a reality and if so how regimental do you have to be with the use of it? Has anyone else used the Penimaster pro effectively post op?
