Seems neat. I don't have any experience with it. Or heard of it like stated above.

But with some of the more simple setups with success. It makes sense to me to go that route. Such as styrofoam cooler incubators. Or small personal fridges.

The price throws me off. And that may be what incubators go for. But other than that it sounds legitimate.

My 2 pennies.
Best of luck to you.
