Come on. Maybe unless you live in India or Africa (and even then, still), $60 is nowhere near as expensive as designing and building your own device.
Not that there's anything wrong with building your own device. Just don't lie about it.

I have a few plants I wanted to monitor, so price is more relevant- $300 is more than I'm willing to pay. I think you underestimate how much of the world thinks $60 is unreasonable for such a device, but i don't suppose there's a way to know which of us is right :)
