I'm just about to launch a new hardware product and was planning on using Kickstarter (it would be my 2nd time), however a partner (and reseller) in the industry brought up the option of them preordering my entire Kickstarter goal so I can get to selling/shipping the final product sooner at retail price.

Seems like an enticing option, my main concern is how much of the Kickstarter market might I miss?

Are people who buy on Kickstarter a subset of those who buy a finished product, or is it an entirely separate group?

I can see pros and cons of both ways, and I know a lot has to do with my specific market (niche time-lapse), but would love to hear any comments or insight. Thanks!
