Very big truth in what u say. I have done one after TA, which is the Wooting Keyboard and it was my last, until now, at least. It's an amazing keyboard and i have several mechanics but i am glad i decided to try this one.
Now for another "KS situation":
I bought a wallet in KS that was funded maybe 2 y or something. It started to fall apart 3 months ago, i tried to contact the seller, got no answer. Searching for something similar i went to Amazon and i found the same EXACT wallet (brand and everything) for a lower price than the one i payed as a 1st tier backer, go figure...
One of the issues with crowdfunding is when they decide to outsource design/manufacturing to china. That's when delays hit and those delays are just enough time for the product to be copied, mass produced and sold off on channels like aliexpress.
