What I did for my indiegogo was update the page with how far along I was ("Today the heat sinks came in! Today we finished machining holes in them! Today the PCBs came in! Today I bought a toaster oven to use for SMD soldering! Today I converted the oven! Today I finished SMD soldering! Today I finished soldering the through-hole parts by hand!"). People were generally happy. When there was a shipping delay because I didn't want to ship lasers out if they didn't have safety glasses included, and the glasses did not come in fast enough, I let people know and this made life a lot easier. Overall I had all of 2 people demand a refund (one was legitimately unhappy with the device, and one was basically trying to keep the laser and also get the money back).

I like to think that I did thing right.
