I'm very impressed by the capabilities. I've seen 'follow me' drones before, but I don't know if I've seen any that are waterproof or as compact as this. And the smiling face on the front is a nice touch. It's still hard to part with my money (even at 50% off) when the ship date is next year though. I've been burned by various kickstarter projects that get delayed ad infinitum.
From the FAQ: "What is your policy on refunds? If you decide to cancel your pre-order before Lily ships, we will provide a full refund to you."
TLDR; during development of the printer, a number of things have changed (including a noticeable reduction in print volume). Refunds were offered August of last year, and the vast majority of refund requests are still pending (and currently half a month behind their own deadline for the latest update.
Not that I have any knowledge on whether the people behind Lily have better or worse communication and management skills, but just because they're happy to offer refunds doesn't mean they'll offer them promptly.
