A bit of an update... First off, the silicone lube makes a HUGE difference. I've worn the HTv2 for 5 days and nights, taking it off only once to wash things up. Only minor skin irritation to report. It hasn't solved my urination problem, unfortunately.
That said, I recently got one of these:
http://www.ebay.ca/itm/261982504146 (S403). A few observations, compared to my HTv2.
The Good:
- The width of the cage is much bigger. I can urinate freely, without having to strain, even with moderate arousal.
- The device is WAY easier to clean. It's open design means that I don't have to do odd Cirque du Soleil tricks with the shower head.
- The weight of the device doesn't bother me at all.
The Bad:
- As others have said, I don't "stick" to the metal. Therefore, it is way easier to come out of the cage. I can imagine that this would happen by accident eventually.
- As provided, the angle of the pin is too high, and it was trivial to completely slip out of the device. I managed to pull out the top at which point it was trivial to sneak both berries out. I fixed this problem with a 2.5lb sledge hammer.

- The cage is too long. When soft, I only fill half to 2/3rds. I'm wondering if a double-ring will be necessary for me to use a metal device?
- Mrs. Wolf doesn't like it. Her initial reaction is: "The plastic device is a fun game. The metal one is more Red Room of Pain" She said that she reserves the right to change her opinion, but that's how it is at the moment.
I have another Chinese device on its way, this one here:
http://www.ebay.ca/itm/331612361225 which is an "A080". Looks like a looker clone. No idea if she will like it any better, but it should give me some better ideas about fit.
All in all, I think that I would buy another HT (v3), if they made the tube a few mm wider, and found a way to fix the flex problem with the ring/tube connection point.
