A perfectly annoying bit of tech. Not a gimmick.
I haven't tried any such devices before, so can't compare it to anything else, but this ingenious sphere works great for me. It's easy to clip on and stays put throughout the night, providing just enough discomfort to keep me off of my back. The part that goes inside the shirt, against the skin, is made of a high density foam that's not cold to the touch or hard as a rock, so I barely know it's there when I'm on my side. But, even with a foam mattress, where my 165 lbs body weight buries it a bit, there's no way that I could sleep with this thing beneath me. And, for anyone who's thinking about giving this as a gift, it comes in a nice case and box.

No More Snoring
As a solo sleeper who struggles with snoring, it's hard to know if a solution is working when you don't have a partner to give you feedback. My issue was always positional snoring—I’d fall asleep on my side but inevitably roll onto my back, waking myself up with a snort. I was desperate for a way to retrain myself. Enter the Calma Clip 2. I was intrigued by its clever design: a small, soft ball that clips onto the collar of your sleep shirt, right between your shoulder blades. The idea is that it makes it just slightly uncomfortable to roll onto your back, gently nudging you to stay on your side without being a disruptive or painful device. I’ve been using it for a full week now to give it a fair shot, and the results have been incredible. The first two nights, I’d wake up still on my side, having subconsciously avoided the little bump on my back. By night three, my body was already learning. The clip provides a perfect, gentle but firm nudge that your sleeping brain really listens to. The proof is in how I feel. I am now getting some of the best, most sustained sleep of my life. I am no longer jerking awake from my own snoring multiple times a night. I fall asleep and I stay asleep. I wake up feeling truly refreshed, with more energy and without that groggy, "I-fought-a-bear-all-night" feeling. For anyone who snores because they sleep on their back, this is the simplest and most effective solution I've found. It’s non-invasive, comfortable enough to forget it's there (until you try to roll over!), and it genuinely retrains your body. After a week, I feel like a new person.

Good if you are a back snorer
This is not a cure for snoring but if you snore mostly on your back this will keep you from rolling onto your back at night and save your partners sanity. It clips to bedclothes and is easy to put on. If you roll over, it is uncomfortable and you will then roll onto your side. For this reason is it is effective. I actually did not understand at first how to clip it on (I probably did not read the directions) but quickly figured it out. It was one of the cheaper anti snore devices I could try and I felt it was worth the money,

Ingenious little sphere that works wonders!
I was told my sleep apena test indicated I slept mostly on my back. In the course of an hour was awakened 47 times. That meant I only slept for 13 minutes in an hour. Thus, severe sleep apena! I tried this 'sphere' and it is fabulous. I can see that someone with a fatty or muscular back could possibly sleep on this and therefore ‘may’ not get the same results. (But I doubt that). I think this ingenious idea should be better advertised. It is amazing. No dry open mouth when I wake; no problem sleeping on my side; and now I remember I have dreams! I went for a year without dreams! It's well made, ever so clever, The shell is hard but not heavy. It is small and light weight to travel with you. Aesthetically, pleasing to the eye. I sent this in but am adding more. I decided to buy 3 extra ‘Calmas’ to make sure I will have extra for myself or to give to a friends. I must make the following suggestion to you. Please spread the word about your product. Advertise on tv, in AARP magazine, in a magazine that is distributed to a company that does sleep studies or doctors’ offices. You must spread the word about your product. That is how highly I think of it. Seriously, the price is reasonable, especially for the quality and look of the ball. But most important this seemingly minor product is a major aid for people with sleep apnea who have a problem only when they sleep on their back, as I do. This saved me the years ahead from wearing the CPAP contraption! Please advertise to a wider audience to help others like me!

I can still sleep when I am on top of it
I find myself sleeping on top of it on my back anyway. I tried and it just didn't keep me from sleeping on my back.

It’s been a life-saver.
Such a simple but extremely effective device. I stop breathing when I sleep on my back. Used to wear a halter to stop it but that was very uncomfortable in most any position. This only bothers you when you need it to, otherwise you never notice it. It’s a godsend.

Calma kept me CALM
I don't usually write reviews. But if you suffer from sleep apnea and don't want a CPAP try this first. I monitor my sleep with a Lookee oximeter. With the Calma, which I used for the first time last night, I only had 2 drops. And they were only to 90%. So I am very happy with the Calma. It kept me on my side to sleep. Effective! I recommend it. Easy to use as well. Update: it has now been a week with Calma Clip. Sleeps scores this week have been excellent. My sleep score last night was 9.9/10! I recommend and endorse this product 100%

Really nice product, improved my sleep
Super happy with this purchase. An obvious improvement over my terrible home made ‘ball taped to T-shirt’ effort! Highly recommend the Calma Clip, I’m sleeping much better now.
