Recommandation for white noise machine

So I never used a white noise machine for my son, but now at almost 16 months, he never slept through the night and I thought I could try white noise. So I would like to hear from you so that I can choose one. I want one that goes on all night long and ideally, I would prefer those that doesn’t connect to the WiFi (unless they are the best loll).

So what are you using? Thanks!
