I'd worked through the whole catalogue before this — strips, a boil-and-bite mouthguard that made my jaw ache for a week, one of those wedge pillows. The mouthguard was the worst of it. I gave up on that within four nights.

This is the first thing I've used that I actually forget I'm wearing. First two nights I was aware of it, third night I stopped noticing it entirely. My wife moved back into our room after about a week and a half. That's the review, really.

Eleven years of earplugs, white noise machines and eventually the guest room. I bought this more in hope than expectation and didn't tell him how much it cost.

Second week in I slept straight through for the first time in longer than I want to admit. He says he doesn't feel it. I'll take it.

I'll be straight — I don't think this is magic and I'd be wary of anyone telling you it is. What I can say after two months is that it's quieter than it was, my wife confirms that independently, and I'm not waking myself up at 3am the way I used to.

Four stars because the adhesive pads run out faster than I expected and I'd rather they included more in the box.

I'm on the road maybe eight nights a month and there was no chance I was taking a machine through TSA every week. This lives in the front pocket of my laptop bag in its case.

Shared a room with a colleague at a conference in February and didn't spend the whole night dreading it. That alone was worth the money.

Worth setting expectations — this was not overnight for us. First few nights I couldn't tell any difference at all and I did wonder if I'd wasted the money.

By the end of the first week it had definitely changed. Not silent, but the sort of quiet where I can fall asleep before he does instead of lying there waiting.

My main worry was that I'm on my side most of the night and anything on my throat would end up digging in. It genuinely doesn't press into the pillow — it's flat enough that it just isn't a factor.

Charging every few nights is the only bit of admin. Minor.
