Yeah its basically the penimaster pro but only a half circle for the base. I wouldn’t get a penimaster they are weak and break alot I dont have time to wait for 2 weeks back and forth from germany for replacement parts. This thing looked a little bit tougher and it doesn’t use rods it uses a single long bolt to tension up or down. I had the original penimaster and a chinese knockoff called proextender and they ended up being the same item so I dont spend 200+ on relabeled cheap china goods anymore. Same with the bathmate and everything else. Its all 20 to 40 dollars direct from the chinese manufacturers and they usually include a shitload of spare sleeves and parts so if it ever breaks you can fix it without customer service.
This thing is actually insanely sturdy and a very hard design with a good tug. Vacuum cap and everything works perfect once you rig it all up properly. Its very stiff but the springs have a good jump and seem to be solid. Only bad thing I can say is the base is improved and it doesn’t burn or ache your base area BUT you have to screw it back down, snap the cap out and flip the extender rod and base upside down or vice versa to go downward or upward. You can’t go upward and have the base downward it just pops off and vice versa. I usually just wear extenders downward so its not a big deal to me but if you switch positions alot then its a deal breaker. I’d give this like a 9/10 due to price and usability. I’ll probably end up contacting them about a full base instead of the half and try to get one.
