What is Reddit's opinion of FYJENNICC Lightweight Premium Chastity Device Resin Male Briefs V3 Transparent (Nano)?

From 3.5 billion Reddit comments

Since you're AUS, I'm assuming you're using cm.

A) when deciding length, Measure your size when you're flaccid, then take a cm off. The more snug the fit of the cage, the more comfortable it is to wear.

B) I would buy a cage that comes with plenty of adjustable rings. Those take the most experimenting to get right. Too loose means the cages slips off or isn't comfortable, and too tight makes for a painful experience.

In general, I recommend a short knockoff Holy Trainer V2/3 for anyone just starting (which, is what you chose, but you selected the long version). It's a cheap small, cute cage that with some small mods can be quite comfortable. For example, I'm about 5.5cm long flaccid. and honestly, a V3 Nano fits me absolutely perfectly. They do come in pink, but you'll have to keep an eye out for it. The one I got, they changed the item, so I can't link it.

As for not having it delivered to you home, honestly, if you order from amazon a decent amount, there won't be anything on the package denoting what it is. So as long as other people don't open your stuff, you're fine to have it delivered. If not, then amazon lockers are the way to go.

Hello, I was hoping you could help me with a few questions.

I currently have a HT v3 knockoff from Amazon: https://www.amazon.com/gp/product/B07QVZK5X6/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

The ring I am most comfortable with is the 50mm one. It is somewhat oval shaped being wider horizontally and has an ergonomic base. It fits well I can just get 1 finger under it when soft. I dont like how it pushes my balls somewhat forward and up though, I think this is caused by the lever effect of the extra at the back of the tube. There is also not enough of a gap between the sides of the ring and the tube so that unless I pull through as much ball skin as possible, it pinches there.

Ive tried wearing metal o-rings for sizing. 50mm is too big but 45mm is too tight. With the above description, would this ring be a good choice? https://www.shapeways.com/product/FSE8LWAAW/cherry-keeper-ring-47mm?optionId=134367256&li=shops

Will it still push my balls forward and up?

If I fit into the nano (amazon link above) just right for length, would this cage be a good equivalent length? What is the measurement from the back of the ring to the tip of the cage? Im hoping it wont bulge out more than the HTv3

Thank you for any insight you can offer!
