I've heard a few things on this recently. Haven't backed it myself as wasn't interested, it didn't solve any problems and seemed to only introduce a problem of having to plug something in just to charge it (It seems to completely negate the benefits of USB-C).
Anyway a few people have mentioned that they won't back stuff etc, so this has clearly hurt confidence. Just wanted to say that there are plenty of genuine companies out there in need of backing to get stuff done, it's up to you as a consumer to figure out the good and bad sadly. But be skeptical.
With this particular project, I asked mainly why they needed funding in the first place. The technology and tooling required are very minimal, and financially it would not cost that much to produce. Therefore the only logical reason I could work out for why they wanted to kickstart it is it's basically free orders for them. Instead of going through the process of manufacturing and marketing, they simply get people to pay for something upfront before any use. I do not like companies that operate in this way, make a product and then try to sell it, rather than selling a product before making. So personally I won't back campaigns that I deem as quite frankly shoddy business tactics. And if anyone else is skeptical then you can use wait for the product to actually be available before purchasing.
So if it's too good to be true? Avoid. If it's something that could easily be done without backing? Wait. If it's genuinely something feasible but financially difficult, then by all means back away!
