Our take on the IP68 Waterproof Smart Fitness Tracker Ring with Touch Display Screen & Portable Charging Case, US Size 12

The Yajisi Smart Ring is a stainless steel fitness tracker with a small touch display built into the band, plus a 300mAh charging case. It logs steps, distance and sleep, and is rated IP68 for swimming and hand washing. At $29.99 at eBay as of November 6, 2026, it is the lowest of the three stores that list it new, so the price is at the bottom of its current range. Treat it as a budget novelty ring rather than a medical-grade tracker.

Questions and answers

Is the Yajisi smart ring worth $29.99?
At $29.99 at eBay as of November 6, 2026, it is cheap for a stainless steel ring with a display and charging case. It is a reasonable experiment, but do not expect the accuracy or app polish of a major-brand ring.
Can I swim with it?
Yes. It is rated IP68, which covers swimming, hand washing and sweat. Rinse it with fresh water after pool or saltwater use.
How long does the battery last?
The ring holds only 18mAh, so expect short runtimes between charges. The 300mAh case can recharge it several times before the case itself needs power.
Does it track heart rate or blood oxygen?
No. The listed sensors cover motion only: steps, distance and sleep. There is no heart rate or SpO2 tracking.

This listing is US size 12 only, and stainless steel rings cannot be resized. Check your ring size before ordering.
