Has anyone had experience with any kickstarter specific newsletter, and what type of project they had?

I am currently considering the gadget flows newsletter as well as backerlands. I am worried that because we don't have a tech gadget that it may not perform as well. Our product is an innovative travel pillow, but for a better understanding you can see our campaign here: http://kck.st/2ytOJyT

Any advice would be appreciated!
