In this video I tested the Pulsetto Fit and Pulsetto Lite — external vagus nerve stimulation (VNS) devices that basically “electrocute” your neck in the name of science. I show exactly how to position it (find your pulse, then move slightly down), how I apply the conductive gel without ending up with a sticky neck, and how the app sessions work. I run through the free sessions like stress, anxiety, sleep and pain, and I also demonstrate why you absolutely shouldn’t start on max intensity unless you want your neck muscles trying to escape your body. After a few weeks of using it, my honest take is: it doesn’t… but it kind of does. I found the sleep session genuinely relaxing (it can feel like a pulsing neck massage), so if it chills you out before bed, you’ll probably sleep better. For pain and stress/anxiety though, I’m not convinced it’s doing anything magical — it felt more like distraction or placebo, and I explain why that “2 weeks to a month” claim is hard to judge. I also flag a few things that made me wary: constant “sale” pricing, being asked to send a draft for approval (I don’t do that), and pressure around affiliate links (I turned that down). Add the £300-ish price and the cheap-feeling plastic build, and it’s not really for me — even though plenty of users say it works for them.
