I certainly wouldn't pay $150 for that, and was asking myself the same ?. It's not going to appreciably increase the value of my home, so an argument that it's home improvement doesn't hold water for me. It doesn't seem to have that much hardware, which would help me understand the price point even if I still wouldn't pay for it.

It simply doesn't solve a problem I have, and at $150, I'm not likely to give it a shot to see if locking my doors manually is really that much of an inconvenience (I doubt it is). I might pay $50, but even then that's a stretch because, as I said, it doesn't solve a problem I've got.
