Bought this through e bay... and wow what a beautiful piece. my wife loves it, but had to chuckle... its less taming the beast and more teasing the timid. feels really good on. I am modifying it tho to accommodate my PA piercing.. warning the stainless steel eats drill bits.. a sure sign of its quality.
Final words.. Exceptional quality for rock bottom price, better than plastic any day.

My wife loves her new pet, especially teasing him!
The beast is simple to put on and does not have any pinching issues, although sometimes in the middle of the night, if the balls are full, the scrotum can get caught, giving non erotic pain until a bit of lube and adjustment is administered.
Most of the time it feels like my wife is holding me, either gently or firmly.
Sometimes, my excitement gets the better of me and the fangs remind me that I could get bitten!
In practical terms, the open mouth allows easy urination.
This is now our preferred device for everyday wear, under tight panties in public and looser knickers at night.
Other devices are used if she is feeling like punishing me!

The Beast is quite a piece of hardware.

The outside is well finished and the connecting point is simple and needs no real confounding lock, like some other devices. The inside is not quite as good, I was expecting something more like a tube, but it's a cast piece, so the outside is mirrored on the inside. The nose and jaw have little pockets inside, which can catch excess liquid.

The teeth and spaces around the teeth are quire arousing. They're not, necessarily, sharps, but pointed enough to tease the head a little bit. Under some pressure, you can pinch yourself a bit - that might be good or bad depending on personal preference.

The ring is well made. I kind of wish I could just get a stainless ring like this to wear all day.

For me, though, the whole thing is a little small or short. Wearing the ring only or the device only is fine, but as soon as I connect the two and lock it into place, the device slowly creeps forward from it's perch. It certainly won't fall off, but some adjustment is needed throughout the day. Not a slight against the device, but an observation of my own use.

Overall, it's quite a statement. Especially when wearing tight underwear or certain thin fabric pants/shorts - you can tell where the ears and snout are, it's quite amusing.
