Not as fun - I don't think it's as fun or rewarding going this way but that's my personal Con to TK.

So make sure your investment strategy is sound and balance risk vs reward.

The risk vs reward just doesn't seem worth it to me (would you pay him $110 if he asked you?

I've looked at these areas numerous times.

Three crowd funding models include Donation Model (you are giving funds, nothing in return - donating to a family in trouble for example), Reward Model (you buy a product at a discount and get it first to help a start up company; no equity, you get products.  

Spread the risk and share the rewards/potential downside.

There were also numerous box-springs, mattresses, etc in the house.
