You are a Portal fan, or you wouldn't be reading this. You will love this toy.
Now, to make this review a bit more useful for those who are not just going to take my word for it (and I don't blame you), let me tell you a few details:
This thing is big. Somehow, after looking at pics and videos, I still didn't imagine it being taller than a few inches. It's almost as tall as my hand (from wrist to fingertips).
It is loud, as another reviewer pointed out. The loudest part is by far the beginning ("preparing") phase; that beep could wake the dead.
The legs are just stable enough. They are flexible (but I wouldn't bend them too far), so the whole thing kind of feels like it might topple over at any moment (a design flaw that is apparent in Aperture's full-size models as well :))
There will be a usb cord sticking out the back. That doesn't bother me personally, but I thought I'd reiterate what is stated in the specs, depicted in the images, and mentioned in a previous review. Just in case.
My unit has a piece that rattles inside. It's probably no big deal, but it's disconcerting. When I first took it out of the box, I was worried that it had gotten broken during shipping. Works fine though.
The doors don't close 100% flush--well,they do at first, but then they pop out just slightly, about a millimeter, mostly on the left side.
Those are all the issues that one might consider negative. As for positives... How do I describe how happy this thing makes me every time I see it sitting there or witness it spring to life?
The night I got it, when my wife came home from the gym, I told her to go check out what I'd ordered. I said it was on my desk. Hearing it attack her as she rounded the corner made me grin like I imagine GLaDOS would if she had lips.
Overall, practically perfect in every way.
Here's a video that gives you a great rundown of the features: [...]
UPDATE (8/13/15):
I just thought I should add a few more details:
There is a button on the back that allows you to manually open the gun doors and a second one to close them. When the doors have been manually opened, the optical sensor is deactivated, meaning that it will not respond to movement. This is useful if, like me, you have it sitting right next to you on your desk but don't want it shooting you every time you turn your head. However, it also means that the turret is in an unnatural doors-open state and takes up more space on the desk. My personal solution, which I thought I'd share, was to stick a tiny piece of Scotch tape (other brands are available) over the sensor on the front (the little black rectangular hole under the light). This makes the "eye" very near-sighted; now I have to put my hand right in front of it to have it activate most of the time but about 10% of the time, when I'm doing a big movement like getting up from or sitting down at my desk, it will activate as well, which is actually perfect in my opinion. The tape is translucent but not completely transparent (transparent tape would probably not have much of an effect) but you cannot see it at all once applied so it doesn't detract from the look. If you were to add another layer of tape, it would probably make it even more near-sighted, and if you were to use opaque white duct tape (I tried this too, though it is more noticable) then it would make it completely blind obviously. Still enjoying this thing two years on.
Update: (3/15/17): Still works. :)

I LOVE THIS
You are a portal fan or you are buying for one.This is a great product and I just love it. It's about 7 inches tall and about 2 inches wide, so if you were expecting a foot tall 7 inch wide sentry gun your out of luck. On average the delay between the words and actual shots is about 3 secs so it doesn't fire right then and there. One thing that I find annoying is that there's a 3 second "cool down time" delay between each trigger. It also doesn't have a battery so it has to be plugged in at all times for it to work. Other reviews say that it's legs are "Flimsy" and " it feels like it could break at anytime" but they are not as weak as the make it sound. when it is plugged in it says preparing 3 or 4 times with 7 or 8 beeps,each beep isn't that loud. Over all this is a good product and would recommend it to anyone who likes portal.
