There's still almost two weeks left on the campaign, so nobody has recieved anything yet (except those that have bought the developer watches from the Espruino store).
That's a message from Kickstarter, reminding you that Kickstarter isn't a store but a way for creators to raise money to complete their projects. Sometimes projects fail (I've had a couple of duds), but since Bangle.js 2 already is over 800% funded and there's still 13 days to go I believe the funds won't be an issue at least. And @Gordon is extremely good at running a campaign, so I'm not worried.
I'd like to back Bangle Js 2 but it says rewards are not guaranteed? For those who back have you received your reward?
