I'm not sure what link you were referring to, but I did notice something new at the top of their page:
https://equity.indiegogo.com/?referral_code=iggheader&utm_source=header&utm_medium=igg.com&utm_content=&utm_campaign=equityI don't think the link refers specifically to Batteroo, but that IndieGogo has this option already available for some time now. I'm not sure if you are thinking maybe Batteroo will decide to head this way.
I also noticed they changed their title to: "Batteroo: Extend Battery Life
Significantly." (instead of saying 800% or 8x or whatever it was before).
As far as Equity crowd-funding goes, if a company like this does decide to do it, it would be a better way to raise funds. At least there are rules and regulations governing securities exchange, share ownership, transparency, etc... and people I assume would be willing to sell their shares in an open market as well. Far better than just handing over money to a company and praying they will deliver a product. Nevertheless, it is still a risk like owning any stocks, especially in a start-up.
Other than that, I'm not holding my breath for any announcements. I think early tests done by Dave and others thoroughly debunked it. Whether they still make money from this or not... I am certain they will. Just stock the "last-minute" items in the check-out cashier line (next to the trash/gossip magazines), put the right price on it, and you'll sell them by the billions to a world full of people who never heard of it. Honestly, how many people would even have a clue?
For example, car dealers, department stores and everyone else still sells these B.S. car electronic rust inhibitors and get away with it.....
http://www.canadiantire.ca/en/pdp/counteract-electronic-rust-protection-system-0477905p.html. They have been for years, and they will keep selling them. Heck, if Batteroo sold shares I would by a boat-load.... This is not the first company to make money off a sham product on the uneducated public.
My parents swear by a product called "AirBorne" sold in the USA to stop colds (
http://www.airbornehealth.com/). It has a huge amount of vitamins and some of it could be dangerous there is no scientific evidence at all that it works (
http://www.webmd.com/cold-and-flu/news/20080304/cold-remedy-airborne-settles-lawsuit#1). Yet it sells by the billions because people still buy this garbage due to the placebo effect. If you are straight-up investor, you buy stocks based on profit potential, nevermind the unethical business practice. As long as the unethical practice isn't detected or doesn't affect the stock price, you are laughing all the way to the bank. Sadly that is the way business works. Unethical practices are the norm unless there is a reason to not do it, if you get caught, or if it affects your bottom line.
