cookie tree — I got the extender with comfort straps. I used it for almost a year. I kept having issues with slippage. So I switched to using the noose & foam tube. I’ve been using it ever since & maintain tension better. However I will say, there is definite discomfort especially after 1-2 hours, & then I remove it for 15-30 minutes, & back on for another 1-2 hours. It does take a while getting used to. When I put it on, I start with low tension, & then after so many minutes I slowly tweak up the tension. I can say that it’s rare I don’t have some discomfort, but I’ve gotten used to it. My skin is very soft & sensitive, and I’ve never gotten the hardening of the skin like some people have mentioned. However I’m still able to work with it.
As far as instructions, you can always google instructions, use TP threads, etc.. The other thing is that it’s just trial & error until you figure out what works best for you. I think the extender is a great PE tool for length if you can find the time to wear it consistently.
