Most "new" products we see are really just minor evolutions of gadgets that have been around for years. But here's one that's completely unlike anything we've used before. Meet Thync, a wearable that zaps your brain to change your mood – like a drug that replaces chemicals with technology.

Before we jump in, keep in mind that, though we cover plenty of science at Gizmag, Thync is a consumer product. And that's exactly how we're reviewing it – much like we would a new iPhone or laptop. We share our experience and make our recommendations, but we aren't writing any research papers or conducting any double-blind studies on it (though the company does link to some of those on its website).

After using Thync every day for the last week and a half, I'm convinced that it's one of the most exciting new tech products of 2015. Like taking a hit of Mary Jane, it can push me from an anxious, over-thinking mood to one where I'm cool, collected and laid-back like a THC-infused Rastafarian. And if I'm feeling sluggish or unmotivated, Thync can also peel that layer away, like the sun burning a morning fog off of my consciousness.

The Thync module itself is a curved white gizmo that connects wirelessly to a smartphone via Bluetooth low-energy. You start by snapping one of two different strips to the device. Each strip has two adhesive pads on it; they each attach to different points on your head (it sounds complicated, but the Thync app has a setup video that makes all of this easy and clear).
