Is the Milavan smart ring worth $33.99?

At $33.99 at Zulily as of November 6, 2026, it is one of the cheapest smart rings available. Expect basic tracking, not Oura-level accuracy. It suits someone curious about ring tracking before spending $200 or more.

Does it work with Android phones?

No. The listed operating system is iOS, so it pairs with iPhones over Bluetooth. Android users should look elsewhere.

How long does the battery last?

The 20 mAh battery gives 5-7 days per charge, and a full charge takes about an hour on the magnetic charger. That is shorter than the 4-7 days premium rings claim but in the same range.

Yes. It is rated IP68 waterproof, so showers and swimming are fine. Avoid hot tubs and deep diving, which exceed most IP68 ratings.

Not built in. GPS comes via your paired smartphone, so you need to carry the phone for route tracking during runs or walks.

What sizes does it come in?

Sizing is not specified in the listing. Check the store page for available sizes before ordering, since a ring must fit snugly to read heart rate and blood oxygen reliably.
