As an entrepreneur who's always on the go, I was looking for something to simplify my digital tasks without adding bulk. The problem was that I kept fumbling with my phone for payments and unlocks, wasting time. This ring seemed like the solution—wearable and straightforward. After using it for a couple of months, I can say for sure it has its moments where it works incredibly well, like during a quick coffee run. But as it seemed to me, it's not perfect; it occasionally glitches or doesn't register taps, which is annoying. The takeaway is that it's a decent gadget for beginners, but it might not be worth it if you need something more robust. I'd recommend it with caution—it's okay, but not amazing.
- Pros: I liked that it's waterproof and can handle getting wet without any issues, which is great for my active lifestyle. It pairs easily with my phone and other devices, making things like paying or unlocking gadgets just a tap away. The design is sleek and doesn't stand out too much, which I appreciate for everyday wear.
- Cons: On the downside, it doesn't always work reliably; sometimes it fails to connect or respond, which can be frustrating. It feels a bit flimsy and not as durable as I hoped, especially for the price. Also, it doesn't offer much beyond basic functions, so it's not as versatile as I expected.
