After unboxing and donning the Phoenix Guardian, I thought I should share some initial thoughts. I've had the Guardian on for the last 7 hours or so and it's not uncomfortable. My biggest complaints are un-scratchable itches, which I suppose I'll just have to get used to, and putting the device on. As I can finally say, the built-in anti-pull-out device works very well, so well that it impedes installation. In fact, even though I checked over the device for burrs or rough edges, finding none, I managed to nick myself by pinching some skin between the top of the cage and the ring. Although I haven't tried very hard yet, I can't even imagine escaping without cutting the lock. Even with the key, I suspect removal will be a little challenging, but nothing I can't overcome with a little practice I hope. I'm going to wear the Guardian to bed tonight, and we'll see how that goes.
