While it’s great that they do so, a few dozen variations of cheap knockoffs at $20 each will go many times further that a 1-for-1 donation deal for a $130 high-end product.
At the end of the day, it’s a (nicely well-made) tin can, battery, fan and Peltier thermoelectric generator, right? A DIY version shouldn’t cost more than $40, and if you have access to cheap manufacturing, much less than that.
(To be clear, I’m not saying not to support these guys, or that they don’t make a good product, just echoing @stefanjones’s point about cheap knockoffs being a good thing.)
