Andrew Liszewski is a senior reporter who’s been covering and reviewing the latest gadgets and tech since 2006, but has loved all things electronic since he was a kid.

It’s not a household name, but Rogbid has been churning out budget-friendly smart wearables for around a decade. Its latest creation capitalizes on the recent trend of functional ring watches, but unlike Timex and Casio’s wearables that don’t do much more than tell time, the Rogbid Fusion includes smart functionality like fitness tracking, heart rate and blood oxygen measurements, and sleep monitoring.

It’s available today through the company’s online store for $49.99 in gold, silver, and black, which is significantly cheaper than Casio’s and Timex’s ring watches that are both well over $100. Instead of a basic LCD display, the Fusion features a 0.49-inch OLED screen used to display the time, date, and various health metrics. It looks a little chunkier than other ring watches that focus on retro styling, but in addition to an optical heart rate sensor and motion sensors used to track over 100 different sports, the Fusion has a battery good for an estimated five days of use, or eight days on standby.

Like Casio’s G-Shock ring watch that debuted last November, the Rogbid Fusion comes with a magnet Milanese strap that’s adjustable to fit your finger so you don’t need to deal with spacers to find the perfect fit. If you don’t want to wear it on your finger, a longer nylon strap can be swapped in so the Fusion can be worn on your wrist like a traditional watch.
