I'm using Inkbirds on everything, so without heat controllers this might not be a good suggestion. But I have had great luck with the alphabet soup brands of knock-off heaters from Amazon. Their wattages might not be accurate (for example a 500W heater is probably just a 300W with a different sticker on the box). But knowing that, I've been pretty happy with mine.

I've had no failures with these heaters over the last 2+ years sample size about 15 or 20:

They're all the same heaters and if you're going to try to regulate with the dial, you might not have a good time. I've never tried it since I have Inkbirds to spare.
