I'm just going to add, what I know, and my experience of Crowd Funding sites, e.g. Kickstarter, and I'm not going to invest in Flow Hive because of experiences with Kickstarter, and a Crowd Funding project I helped with:-
I backed a company, (well known in gadget circles from Barcelona called IDAPT) I already have an IDAPT charger, so I thought the MODULOs were a good idea! Because it's from an established well known company.

Kickstarter takes a percentage of the Pledges, Payments are collected through Amazon, 1 month after the Project has been successfully funded, if the project is not successfully funded, no payments are made.
IDAPT Modulo was successfully funded, but suffered late delivery, poor communications, clearly they had technical and logistical issues meeting the demand, after the shipment of MODULOS, they stated there would be issues, meeting the other accessories, e.g. solar chargers.
The products shipped do not work or charge items correctly, there is no re-course, no distance selling regulations, no refunds, Kickstarter are happy bunnies because they've had their money.
and it now looks like IDAPT have gone away, possibly bankrupt....
I'm not stating this could happen to the Flow Hive, BUT buyers' beware, or INVESTORS be aware, they you are investors, and as with all investments......
I'm out of pocket by $85, some poor soles, are $250 out of pocket, and have nothing from Kickstarter/IDAPT-Modulo!
So seems like an ideal place for scammers to take your money and run! Not stating here, that Flow Hive is any such thing!
Be warned, I'd wait until it appears in the Mann-Lake or Thornes catalog!
