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.

Works as expected, easy to use
I've had this ball for about a month and a half now. It is nicely made and clipping it into a shirt is easy. It woke me up a few times during the first couple of nights, but I no longer notice it. Most importantly, it appears to work based on my wife reporting noticeably less snoring! It's a tad on the expensive side for what it is, but still worth it for me.

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!

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,

Review of Calma Clip (After 1 Month of Use)
I have moderate positional sleep apnea — only an issue when I sleep on my back. I tried CPAP for a week, but it left me more tired during the day and was just too uncomfortable. The Calma Clip, on the other hand, has been a surprisingly effective solution for me. I’ve been using it for about a month now. My Oura ring shows clear improvement in my sleep quality, and more importantly, I feel noticeably more alert and awake the next day. It took a few days to get used to — at first I’d wake up when I rolled onto my back — but now I don’t even notice it. Either I’ve adjusted or it’s doing its job subconsciously. The design is simple but smart. It stays in place all night, and while it’s a small extra step to clip it on each night (or keep it pre-attached to a dedicated shirt), that’s a minor tradeoff for the benefit. I know CPAP is necessary for some people, but for my specific case, this has been a better solution. It’s more effective, more comfortable, easier to travel with — and way cheaper, though honestly, that’s just a bonus. What matters is that it works.

Works for Wife!
My wife has the problem of wanting to sleep on her back where her breathing then is not good. She has tried a variety of things like 3 tennis balls in a shirt she made. Tried the pillows to keep from moving to her back. None were very successful. This clip on ball has been the best device she has tried and after several weeks we are confident it is working. It doesn't bother her and yet she sleeps on her side where she is very quiet. Her sleep scores with her Fitbit have consistently been good in the 80's and even the lower 90's. The Calma Clip v2 is so simple and works so well it is amazing it took us so long to find it. Obviously it's happy for me also.

Help not to sleep on back
I’m not wowed, it’s uncomfortable, and in the night when turning on the back, I wake up and accept this uncomfortable situation and fall back asleep on my back.

Great product -
Have shoulder/scapula issue from overextending right shoulder/sleeping on it incorrectly. Ball smartly clips on shirt easily and firmly. Used this product immediately and it definitely helped me not sleep on bad right side. I then actually used it when woke up to work out that spot by carefully rolling that zone (kind of like rolling pad, but more targeted). Like it a lot.

Braucht kein Mensch, konnte damit überhaupt nicht mehr schlafen. Leider Rücksendung verpasst, wie ärgerlich.

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.

Value for money
Reasonable size for use, but I prefer a magnetic ball.
