Hi everyone. I just wanted to let you all know that IndieGoGo have begun refunding backers of the Astro Slide crowdfunding campaign, but you have to contact them in order to initiate it (they just refunded me).
You need to go to IndieGoGo's Trust and Safety page, and contact them directly.
They told me they are using the frozen funds from the campaign, so I don't know how many people can be refunded. If you never received your device and want your money back, you should be quick!
