Have had one of the cheap 5v ones from Alliexpress under the bed for six weeks. Tried it last year, but couldn’t sleep.
This time round I persevered, and it is easier. Waking up less, but no real idea if it has an effect. I have noticed that I am not tired during the day, no matter how many hours I've slept.
