My personal review is this.
Positives
Very strong trustworthy hold with no slippages so far and none expected as there is a grip all the way down the shaft as well as the silicone sleeves being almost adhesive to one another, not as in they literally stick but they don't slide off each other if you know what I mean.
Potential negatives
It is a bit strange to sit down with it on, it's something I'm going to have to get my head around. probably because I've been wearing it attached to my leg when there is also the option to have to strapped around the waist just like the
Phallosan.
You can hang
weight more comfortably with the chain due to the grip being further along the shaft which gives you the added expressive stretch.
The real thing I tend to have an issue with, that may be exclusive to myself, is the seal of the first
sleeve you put over your glans.
You see, a little backstory here, I had a condition known as Phimosis all my life until the age of 14 when I managed to stretch the foreskin out manually as doctors were refusing any sort of medical intervention, however despite this I still have a sort of ring of foreskin that sits beneath the glans of my penis even when erect, probably the remaining phimotic gland. As a result of this it is difficult for me to put the glans
sleeve on without any air being left in the
sleeve, but this will not apply to you as judging by your previous profile pic I see that you are either circumcised or you don't have the foreskin issue when erect, so that's not of concern.
Another thing you need to make sure of is that when you apply the cup with the second
sleeve is to get your glans as far into the cup as you can so you don't need to use as much pump to get it in as this can lead to some swelling on the glans.
In conclusion
I'm pretty sure all the difficulties that I've faced are as a result of my own anatomy doing my dirty rather than the device being faulty in any way. I personally love the cups and find them to be far superior to the PeniMaster Pro.
I will link you a video review on YouTube Baseem made that talk about the product and his opinions.
And to see how you can put it on then sign up to his free course here, he doesn't charge anything for this and the videos on there will show you everything that I've talked about.
Quick Disclaimer
I know I have spoken a lot about Baseem and I have even bought his product. I am not paid to say anything. Nor do I agree with everything he says on his channel related to PE. I just think he made a good device with the Best Extender and he's the only one that talks about the Extenderz Pro devices. So please no one bash me for acting like a Baseem fanboy, I am most certainly not.
