Wow, this is really an interesting product....but I'd have to say it's a bit scary as well. I would be afraid of impaling my partner with the rod and not know it until it's too late. I mean, in the heat of the moment and all. I'd be so afraid I'm going to town and the erection rod slips through and seriously hurt my partner. I know they say they've tested them, but as with all packers & stp's they start to wear out a bit after wearing them day in and day out. I just shutter at that thought. The erection rod scares me too much.
As far as it working, I really can't say how well or if it would work. It looks like it would kind of work like a whizpacker. Just position it and go. If that's the case, woohoo! That would be great. However, I would concur with you about it being hollow and being flimsy.
I'd love to order one to try it out but the amount of money they are asking is tremendous then having to pay for international (they are from Singapore) shipping on top of it. It's gets to be an expensive experiment.
Thanks for pointing this one out. I am always amazed at the innovations that are out there for us Transmen.
