If you've never lost your house keys twice ($75 per visit for a locksmith) then it's not worth it. However, you could give multiple people access to the door this way, which would be cheaper/easier than making copies of keys.
Also, with normal keys if you lose one you have to replace the cylinder and all the keys if you're worried about someone using the lost key. This would prevent that expense.
I will say, though: if $150 is the discount price, i'm afraid to learn what the regular price is. Businesses seem like the only place this becomes cost effective.
I hadn't thought about the multiple people access problem since I've never needed more than one set of guest keys at a time, and the offices I've worked in were all big enough to use keycards.
Come to think of it, the market for 'Needs to give multiple people rotating revocable access' is a great fit for AirBnB type services.
When I was 16, I was given a car without keyless entry and I was willing to pluck down $200 (that included installation) for the luxury.
I could see spending $150 to get similar functionality plus the ability to unlock my home remotely and check the state of the lock on the only door I enter/exit from.
My family shares a vacation home up north and I'm tempted to buy this for there as well. Because of its proximity to town (two blocks walk) we've already had plenty of trouble with people locking themselves out because they're not taking their car to the tavern in town and simply forgot their keys in the process. We'd have to get in the habit of only using the deadbolt, or replace the door handle with a non-locking door handle, but it might be worth it to me.
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.
Since no one is forcing you to buy it, I would simply suggest not buying it and going on with your life.
Perhaps that sounds harsh, but there are plenty of products out there that cost a lot of money (much more than $150) which won't bring you any additional value.
The new Lockitron will certainly bring value to a lot of people, including renters.
