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.

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.

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,

Convenient solution
Surprisingly, it's a really good solution. The packaging was beautiful (I would say it's giftable, but it sounds strange). I love the case (good for traveling). The design is perfect - the softer half of the ball makes it not painful to turn around, but because of its hard plastic half sleeping on a back is impossible. I also really appreciate that it's easily movable from one item of clothes to another.

Side Sleeping Sleeping Positioner Perfection!
When I was looking for a side sleeping positioner, the options were rather disappointing. Inflatable backpacks, tennis ball sewn into a t-shirt, backpack with a tennis ball, etc. Either the product would was bulky and prone to deflation, required you to wear the same t-shirt nightly, or was likely to slide around and not work. The Calma Clip solves all of those problems. Nothing to inflate, takes 5 seconds to clip it to the back of any t-shirt or nightgown of choice, and go to bed. And, it just works as it isn't noticable when on your side, but if you try to roll into your back, it is so uncomfortable that even when asleep, your body isn't going to want to do that. Absolutely perfect and at a great price compared to other options in Amazon!

Works if you are a light sleeper
Would have worked for me, but I kept finding my husband back on his back with a ball sticking between his shoulder blades and he slept right through it.

Miracle ball
I have atypical sleep apnea that restricts my breathing when I sleep on my back. I took a sleep study and they wanted me to use a cpap, but I wanted to try a positioner to keep me on my side. Without knowing exactly what I needed, I decided to try this clip for price and ease of use. The first night, I was impressed with the simplicity, but didn’t have much hope until I woke up the next day refreshed and with a 95% sleep score on my watch. It’s only been two weeks and my oxygen troubles are a thing of the past. This simple little gadget has dramatically improved my life and saved me money and aggravation. I recommend it for anyone who snores or gets poor sleep.

Damit kann man dann gar nicht mehr schlafen
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.
