Rogbid R2 smart ring now available to pre-order at low price

According to the product listing, the wearable can track health metrics like resting and dynamic heart rate with ±5 bpm and ±20bpm accuracy, respectively. We have not tested this watch, so it is unclear whether this accurately reflects the ring’s performance. You can also use the gadget to log exercise, monitor your SpO2 level and sleep quality, and track your calorie intake and step count. You can connect the smart ring to your phone via Bluetooth 5.2, allowing you to view the collected data in an app. Presumably, this is Rogbid’s app, and it is unlikely that there will be any integration with Apple Health or Google Fit. Rogbid claims that a 23mAh battery allows the ring to run for seven days with typical use, though it is likely less than this.

The Rogbid R2 Ceramic Smart Ring is available to pre-order at Banggood for the discounted price of $37.99/£30.47/€35.23; the product is listed with an RRP of $89.99/£72.17/€83.45. The company ships from China, with US customers given an estimated delivery date between late April and mid-May. Given Bangood’s poor reputation when it comes to returns, we recommend that you consider purchasing an alternative product like the Oura Ring.
