It's not that it is better, it is that it is different - it pulls different; and so yes, lol, in a sense a bit better. But it is BEST to use all of these things. The doctors ( all of them ) are not experts in these devices nor do they have time tested, hands on, experience with them and how they all function. That's where some of us come in; to help each other out. What they ( The Doctors ) do know is: Hanging and Stretching ( both Pre & Post ) surgery has shown benefits.
To elaborate further a bit on the doctors and the devices ( lets call it speculation for legal safety ): these doctors have to be somewhat careful with what and how they recommend certain activities as well as certain devices. FOR EXAMPLE: The green noose from Zen, which is a great little device, is now no longer given out by a "particular" office due to the amount of complaints of uncomfortableness as well as self described misuse. And when I say Self Described - what that means is: unbeknownst to the describer, they are describe misuse in some way. ( IE: leaving on too long ) So therefore - that is to much risk.
OK OSLO, let's talk Phallosan. Which I hate btw, but I've had one; So i can discuss. I only hate it because its fucking cumbersome and ripped the damn thing 3 times. But it did work great as a stretcher and it was very concealable ( better than a lot ). If you are using only this, then YES you need to be incorporating some hanging into your life - but no need to go heavy ( see my previous posts ). When hanging - there are a few devices that are great, rotate them all. Think of it like going to a gym - Do you do ONE chest exercise and go home or do you do a few ?
For time, for up to the two hours per day. start with 30min and see how you feel. then go 45 and then an hour and so on. I think you will find that at the lower end of the weight poundage you can hit the 2hr per day pretty fast, just don't jump right in. lol. Get comfortable. As I mentioned before; for clamp style devices that go on the shaft, you will be able to do more weight, but try to not go to heave. For head/glans clamp style devices or Nooses you will not be able to go super heavy and shouldn't, the pull is enough, go for time. And for Vac Devices; Some people can go heavy and some stayed light ( I always got blisters ) - my advice is to keep it moderate to light and go for time and take it out frequently to get blood.
