Smartwatches have come along way since the first Apple Watch arrived on the scene more than a decade ago. However, despite how ubiquitous they’ve become, they’re still nowhere near as discrete — or long-lasting — as a smart ring like the Samsung Galaxy Ring. Thankfully, if you’re looking to ditch the watch, Samsung’s first-gen smart ring is available with a $100 gift card at Best Buy and Amazon, where you can pick it up in a variety of sizes starting at $299.99 ($100 off), an all-time low.

In many ways, the Android-only Galaxy Ring is more of an accessory for existing Samsung users than it is a standalone device. It’s not as a capable as the Oura Ring 4, our No. 1 pick for the best smart ring, though it does showcase excellent hardware and comes in wide ranges of sizes, from 5 to 15. Plus, unlike the Oura, the Galaxy Ring provides standard activity and sleep tracking without requiring you to pay a monthly fee. That’s a boon for anyone with subscription fatigue.

In terms of basics, Samsung’s IP68 water-resistant ring can measure your blood oxygen level, skin temperature, heart rate, and track your steps and workouts. That being said, you’ll need a Galaxy phone to leverage all of Samsung’s ecosystem-centric tricks, including the ability to access insights about your quality of sleep and Samsung’s Energy Score feature, which attempts to quantify your fatigue levels. If you own a Samsung Galaxy Watch 7 or Ultra, you’ll even get several additional days of battery life, thanks in part to the way Samsung’s Health app prioritizes which device’s sensors to pull from.

All that is to say that the Galaxy Ring remains best suited for existing Samsung users, rather than those tapped into other ecosystems. But if that’s you, the current promo is the best deal we’ve seen.
