Piano Potato R16 Ultra-thin Smart Ring: Ultra-thin and comfortable design
Meet the Ultra-thin Smart Ring – not just another piece of tech jewelry, but your sleek, everyday companion that doesn’t know the meaning of 'bulky'. Whether you're hitting the gym or just hitting the couch (no judgment here), its waterproof design and comfy fit make it a no-brainer for both men and women. And hey, it’s not just about looking good; this little gadget keeps tabs on your steps, heart rate, calories burned, and how far you’ve wandered (intentionally or not).
But wait, there’s more – it doubles as your sleep detective, breaking down your night into deep sleep, light sleep, and those 'why am I awake at 3 AM?' moments. Ladies, it’s got your back (or rather, your wrist) with health tracking that includes period and ovulation predictions. Fancy controlling TikTok or snapping pics without touching your phone? Air gestures have got you covered. (Yes, it’s as cool as it sounds.)
No sneaky subscription fees here, and with a battery that lasts up to 7 days, it’s the gift that keeps on giving – perfect for any occasion, or just because you deserve it.

As a freelancer who values both functionality and aesthetics, I bought this ring hoping it would blend seamlessly into my daily life while offering advanced health monitoring. The reality is that it does a lot well—it's super thin and comfortable, and I've enjoyed tracking my walks around Denver without feeling weighed down. The heart rate and calorie tracking seem reliable during my home gardening sessions, and the women's health features have been a pleasant surprise, helping me stay on top of things. However, I expected more accuracy in the sleep analysis; it often gives vague readings that don't match how rested I feel. The gesture controls were a letdown; they're not as intuitive as advertised and can be frustrating when I'm trying to snap a quick photo without fumbling. Overall, it's a good device for someone like me who's tech-savvy but not perfect. I'd recommend it with caution, especially if you're looking for something super precise, but for general fitness and style, it holds up well after a couple of months of use.
- Pros: I expected a comfortable and stylish accessory, and it truly delivers on that. The fit is super snug and lightweight, making it easy to wear all day without any bulkiness. It tracks my daily activities like steps and heart rate accurately, and I appreciate the health insights for women, which feel personalized and helpful. The battery life is impressive, lasting nearly a week without needing a charge, and I love that there are no extra fees to use it.
- Cons: I expected more from the sleep tracking; it seemed to me that the breakdown of sleep stages wasn't always precise, and I found myself questioning the data during those late-night wake-ups. The air gestures for controlling my phone were a bit finicky and didn't work as smoothly as I hoped, often requiring multiple attempts. Also, while it's waterproof, I noticed it can feel a bit delicate, and I worry about durability over time.
