The difference between how a stretching device attaches to facilliate its stretch is what is significant.
Andro Penis, Jes - or any of those loop based units are going to cause problems, unless you get really good at wrapping. Even then.
The flatter silicone band of the PeniMaster is easier on your circulation and dorsal nerve, etc. Less wrapping is required, but the straps do break and are a pain in the ass to replace.
I personally think that the vacuum based means of attachment (such as the one at autoextender.com), make the best sense - and are less expensive. Provided that one takes precautions against fluid build-up/water blisters, the circulation - and therefore the overall health of the penis - is improved. Circulation is huge in my view.
Any of the other ways of attaching clamp down on the head and restrict circulation.
MrTips your careful observation of PI’s and your responsiveness to them is very good to read about. Many get overeager for gains or read some prescribed thing like “Wear 6-8 hours a day to get gains.” and then ignore their own body’s responses.
If morning wood stops (for example) you are overtraining, and possibly doing damage.
We must be alert to the bio-feedback signals our body sends us and adjust accordingly.
It’s nice to get bigger, but most important: you want it to work and work well.
