The fact that the
Pritect is such a simple device means there's not a lot that you can do wrong. The design is simple and it works effectively. You can have the cover misaligned by a few inches and it is just as functional as being properly aligned.
The main issue I found is more of a conflict; it can't be used at the same time as a Nyko Zoom. Given that the minimum distance on the Kinect sensor is a bit much for your average living room or bedroom, the Zoom is a fairly popular accessory. However, if you have a Zoom on your Kinect, you'll have to remove it to use the Pritect. This means you're basically swapping them out for each other. Not a huge issue, just something worth mentioning.
The other issue I noticed is that even if you don't have a Zoom, when your Kinect is in use, you have to find some place to store your Pritect until you need it again. That might sound a bit petty, but it seems that it would be a small matter to make it reversible, such that when you want to use your Kinect, you would just remove the Pritect, turn it to face the rear of the Kinect and put it back on and strategically placed holes in the back of the Pritect would allow the Kinect to do its thing.
I have been called paranoid. On more than one occasion. However, I take security seriously. Many of those who say I'm paranoid simply don't know how easily privacy can be breached. If you want to keep your private life private while you're not using your Kinect, the Pritect offers that... and some piece of mind.
