Amazon Prime Day is right around the corner, so the deals are already coming in hot. For instance, the Oura Ring is up to $100 off. The discount depends on which design you go for. The Stealth Horizon design is $350 in all sizes, while many standard colors are $300. The gold option, however, jumps up to $450. The prices also fluctuate depending on if you choose the rounded Horizon design or the more blocky Heritage design.

For the uninitiated, the Oura Ring is a smart wearable that tracks activity, sleep and more. The main benefit of choosing a smart ring over another type of fitness tracker is portability. It’s a lightweight ring, so after a few days you forget it’s even on. We called the Oura Ring the “perfect wearable for people who don’t like wearables” in our official review. It even made our list of the best sleep apps and gadgets.

The device monitors over 20 biometric signals and is particularly precise when reading a pulse. The Oura Ring is also compatible with most of the most popular fitness-tracking apps, like Apple Health, Strava and Google Health Connect. Many of the designs are quite fetching and allow the device to easily pass as a regular non-techy ring.

On the downside, a bunch of the ring’s features are locked behind a subscription paywall. You get a month free with the initial purchase, but after that it’ll cost $6 per month. It’s also worth noting that this deal is for the third-gen Oura Ring. The fourth-gen device officially releases on October 15 and it’s smaller, with more tracking capabilities.
