Is the Letsfit YoR Smart Ring Worth It? An Honest Review

Skip it if you want GPS or a screen. The Letsfit YOR LR-08-SL-CASE Silver Smart Ring is $57.75 and it does two things well: sleep tracking and step counts. Everything past that is a stretch.

What's Actually Inside the LR-08

The YOR line comes in a few finishes we carry right now: the Silver LR-08-SL-CASE in Size 8 at $57.75, the Gun Metal LR-08-GM, also Size 08 at $57.75, and a Silver Size 7 model built around body and sleep tracking, also $57.75. Same internals, different shell and sizing. It measures resting heart rate, sleep stages, and daily movement, and syncs to a companion app over Bluetooth. There's no display, no speaker, no GPS chip. That's the tradeoff for a ring this size.

Battery life on rings in this class typically runs 4 to 7 days between charges, since there's no room for a large cell. That's the category norm, not a Letsfit-specific spec sheet claim, and it's worth knowing going in if you're used to charging a watch nightly instead.

Sizing: 7, 8, and Why It Matters More Than Color

Rings only work if the fit is close to exact. Loose, and the sensor loses skin contact overnight and your sleep data gets noisy. Too tight, and you won't wear it. We have Size 7 and Size 08 in stock. If you've never worn a ring before, get measured at a jewelry counter first: ring sizing doesn't map cleanly from shoe size or "small/medium/large" the way a lot of wearables do. Between the two colorways at Size 8, the Gun Metal LR-08-GM and the Silver LR-08-SL-CASE are functionally identical. Pick on looks.

Where a $57.75 Ring Loses to a Smartwatch

If you want workout GPS or want to see a message without pulling out your phone, this isn't your device. For that, we'd point you to the Invicta I-Tech 2 Smartwatch at 45.6mm, priced at $88.99, which adds GPS and heart rate on a screen you can actually glance at. It's bulkier and it needs a nightly charge like most smartwatches, but it does more per dollar if screen and GPS matter to you. The ring wins on comfort and sleep tracking specifically, since a device on your finger disturbs sleep far less than one on your wrist.

There's also no blood oxygen or ECG feature here, features that the premium ring competitors in this category (Oura, Circular, and similar) build their pricing around. Letsfit isn't trying to be that. It's a budget entry into a category where the established names typically sell for well over 200 dollars.

Who This Is Actually For

Buy this if you already know you want a ring, sleep tracking is your main use case, and you don't want to pay premium-ring prices to find out if the form factor works for you. Don't buy it expecting smartwatch features in a smaller shell. The app is functional but basic, and the closed ecosystem means you're locked into whatever Letsfit supports on iOS and Android going forward.

The three variants we stock cover Size 7 and Size 08 in silver or gun metal, all at the same $57.75 price point, so the decision really comes down to fit and color rather than feature tradeoffs between them.

Buying It as Overstock, Not Retail

These three are new-in-box overstock, not open-box returns, which matters more for a ring than for most electronics: you're putting this against skin for a week straight, and a previously worn unit is a different purchase than a sealed one. Check the listing photos for sealed packaging before you buy, and confirm the exact size in the title matches what a jeweler measured you at, since Letsfit doesn't publish a half-size chart the way some ring brands do. Because these are overstock units rather than current-season retail, expect the box and manual to be functional rather than polished, and expect app setup to be entirely on you with no in-store support.

One more practical note: pairing is done through the Letsfit app, not a generic Bluetooth menu, so budget ten minutes for setup the first time. After that it stays connected in the background like any other tracker.

The Bottom Line

At $57.75, the risk of trying a smart ring for the first time is low. If sleep and daily activity are what you're tracking, the Letsfit YoR Silver Size 7 or its Size 08 siblings will do that job without asking you to charge anything nightly or learn a new watch face. If you need GPS for runs or want notifications on your wrist, spend the extra thirty-some dollars and get the I-Tech 2 instead.

Check current stock and exact sizing before you order: ring inventory moves fast in single units.
