We've used Farberware electric percolators for 40+ years. When one dies, I have to rush to get another one as it is the only way DH wants his coffee. He insists that the coffee is hotter in percolators than in drip machines, and he wants his HOT.
If your machine is working properly, luvstitches, it will stop perking when it is done. Then if you wait a few minutes, the water still in the basket will drip down into the pot and you won't have such a drippy mess when you remove the basket. Leave it plugged in to keep your coffee hot.
Strength depends on how much coffee you start with and I think it's a matter of trial and error to get it the way YOU like it.
