The Phallosan is fairly expensive for an extender, don’t rush into the purchase if you’re unsure or unprepared.
Penimaster looks the same as X4 and the phallosan is definetly more comfortable than that (IMO). Even with their multi support grip, I found it hard to continually wear, where as the Phallosan I’ve been able to get to 10hrs of almost continuously wear a day (minus pee breaks and such).
The belt is a elastic cloth material with plastic clips, the ring is a foam which I assume to be hollow based on it’s flexibility and soft squeezable nature. The bell where you penis fits inside and the tension part are made of different types of plastics which through my use and check are well constructed and fairly high quality. The condoms and protector cap are made of a type of silicone I believe. Apparently all materials are medical grade and non allergic - I’ve had no issues so far.
If you want my honest opinion on the device and you’d like to wait I’d like to use the device in my routine for at least a month more before giving any kind of actual positive review. Right now I have alot of good things to say but that could change after using it for longer periods of time and testing more in terms of durability and performance.
