I tried an electric pressing comb a couple of times but it didn't get my ends smooth. So now I use a flat iron. The results aren't as good as when I went to the salon for a press and curl ever two weeks back in the day, but that's because I use significantly less heat but my hair always reverts, unlike when I was younger. I think my results would be better if I cranked it up a bit (I don't use a blowdryer) and used less heat protectant, but I'm still too scared and it gets straight enough for my liking.
