Go through and read the posts. Doesn't seem like a single person was happy with their lockitron. Some are still waiting for theirs to ship... It's a dud.
Shipping delays for kickstarted products are not a new or unexepcted thing nowadays.
A year and a half later and I still don't have it. Communication has been pretty bad, with many blown dates, infrequent messages, and a dashboard that often showed "ship by" dates that were months in the past. Now they're switching my order to a completely different product that I'm not sure I want.
Pre-orders have risk too, but not of even remotely the same magnitude. This behavior might be reasonable for a crowdfunded product, but not for one where the product is supposedly done and shipping imminently.
