About time I posted a review!
This cage is a very different one to my usual 'Cobra/Python' styles and it feels very different to wear.
Ok, so it's not resin, but some form of moulded plastic. Not the horrible hard plastic, but not too soft either, and it has a smell I recognise but can't pin down.
Price was very cheap (I'm a cheap sort of guy sometimes, but not always) at under £14 delivered from eBay and I went for the smallest 'nub' size.
It comes with the usual 4 ring sizes and a barrel lock with two keys (amazing how almost all the chastity cage locks can be opened and closed with the same key.....).
So far nothing special, but... the cage works by sliding the 'cock cover' into a channel in the ring, and passes back beyond the ring, into your body, well, groin, to be precise.
So here it is in real life:

Initially I was a little disappointed as it looked bigger than some cages I already own

However, the 'cock cover' (I don't know what else to call it) was intriguing

Here you can see the keyway/dovetail that the 'cock cover' slides into. Note the shape and edges, we will talk more about those later.
I selected the second smallest ring, slid my cock and balls through and then tried to figure out to manoeuvre the cock cover into place.
This was actually much easier than I'd imagined - squeeze the tip of your cock into the 'tube', aligning everything to the opening at the tip, then gently push the assembly backwards until it engages with the keyway/dovetail.
Once engaged I found everything went together very easily, then applied the barrel lock and it was on!
Immediately it felt very different - instead of squeezing my cock into a small space, with the cage staying on the outside, part of the cage actually goes into your soft area. This means that the rearmost tongue of the cock cover is behind the ring and folding your skin under itself - if that makes any sense?

you can see the shape of the plastic tongue appearing to be under my skin, by my finger (excuse my terrible manicure!)
It was quite an experience and I realised that far from being bigger, this cage was significantly smaller in how it fitted.
So what's it like to wear?
It's very snug indeed, but not so snug as to be uncomfortably tight.
I have worn it now for 3 days and slept for two nights with it locked on, and it feels great. In fact, now my body has adjusted to the different feelings I almost think its more comfortable that some of my other cages.
Another unexpected bonus is that the cock cover ensures everything stays aligned so that going to the toilet is not only easy, its very clean and tidy too - no spraying or dribbling! A very good outcome!
I think the cage needs a belt (I'm using cord for now) to hold it snuggly in place, but that's a minor point - tights or panties do the job almost as well 😁
Also I would like to say that unlike my cobra/python cages there was no painful pinching when setting the cage into the ring - you know the bit where those locating lugs always catch your skin as you try to line everything up! (or worse, just as you've slid the barrel lock into place and you're in a mad panic to get the thing off again before you get a blood blister!). This cage was so easy to engage and lock in place.
How is it as a chastity device?
My experience so far is that it's almost too good!
To explain: with all my other cages there was enough space for me to become aroused, even if only a tiny bit. My cock could swell up and push hard against the cage. I actually quite liked this feeling, especially when waking up to an almost uncomfortable 'morning glory' that was forcefully held back by my cage.
But with this cage, no matter what I try or do, there's not even the hint of swelling, let alone any hardness. I think it might be due to how the cage fits, under my skin, but can't say for sure.
Also I did experiment with a magic wand and couldn't get anywhere near orgasm - even after 10 minutes of trying!! I'm not saying it's impossible, I'm sure I could get something to happen if I applied max power for long enough, but it is very effective - at least it is for me, your mileage may vary.
So, no arousal, no easy orgasm = chastity successful!
You do get (I got) a lovely pool of pre-cum building up at the tip - ideal for tasting or simply dampening your tights/panties!
Can you pull out/off?
No, at least I couldn't and certainly not if you care about your cock and balls!
I did my usual tests to see if I could pull my cock back out through the ring, but the cock cover actively prevents this as your skin is folded over itself and trapped behind/under the ring.
Again, others may have a different experience and as I'm un-circumcised that may also be a factor.
Are there any bad points?
Ahhh, well this is where we go back to the material used and those keyway/dovetail edges I mention earlier.
When I attempted the 'pull-out' I discovered that there was just enough of those sharp edges protruding into my flesh that it all got exquisitely painful very quickly! Not only did I stab myself on the pointed corners, but when I relaxed my grip, the edged closed down on my skin and pinched it!
The fix is easy enough, very fine sandpaper (wet and dry) type - often supplied with cages these days) and a gentle rounding off of the two points, plus a smoothing of the sharper edges. All good now.
Colour choice was limited to pink or clear (I'd have loved black to match my other cages) but that's a very minor thing.
Conclusions?
I love this cage, I really do! And I hope it will continue to perform as well as it has so far.
I am planning a more strenuous self-bondage session soon, which will test the cage's durability, comfort, and effectiveness.
For the money I think it's a great cage and would recommend it.
Play safe
