How did you find a manufacturer willing to build your product? Did you negotiate the price per unit?
Do they require a minimum purchase amount (ie, like 1000 units)?
If you do not have enough backers, are you planning on using your own money to buy up to the minimum purchase number, or cancel the entire project?
How do you plan on validating the build quality before settling on a specific manufacturer to build your product?
We have already built a final prototype that looks and works like final product together with our plastics manufacturer. Circuit boards from Pcbway currently but larger order will come from other company most likely. Again there are many. And same with injection moulding; lots of companies do it.
I think we will reach crowdfunding goals but if not we may get external funding.
Have you considered launching on Kickstarter or another crowdfunding site?

Spent around $50k of my own money to seed fund it.

Was it worth it in the end for you?
It’s actually not about time but about energy levels.
To be able to accomplish this, you setup your life to have maximal energy level balance throughout the day.
For me that meant to unfortunately leave my girlfriend at home almost every evening the past year to get a few hours in almost everyday until I was done.
This also included eating the same food (ready made from Lidl) everyday and just saying no to everything and everyone all the time.
I also recommend that you try to take as little responsibility you can at work and perhaps working from home if possible, where you then use half the day for your own stuff.
One of the few benefits of this lifestyle/endeavour is that you have an income while trying your startup idea.
