Got a seed starter electric from a yard sale for 1$ is it any good?

heated cloner anyone ever try this?

They work, but work best in cooler environments. If you use them somewhere that is already 60+ you might burn up more seeds than you germinate. Humidity is good for clones, but bad for seedlings and roots.

I guess that's good for a winter cloner it gets cold .
in the summer it shouldn't be a problem.
