Yes it is good, that’s why I put it in this topic. But only if you don’t bother a little breeze going over you. You can set the fan very low, you won’t feel it but it still works.
I occasionally have to change the temp. But that is user error, when you’re cold going to bed, you tend overcompensate to warm up and fall a sleep.
There are buttons with different built in timers. Max hot only runs for 10min at 45c. That’s a good thing.
They are expensive, but I would buy again.
You can also make temperature curves when it automatically changes temp over a set period of time.
