What to know before buying
Listing details to confirm
The listing recommends buying a sizing kit before the ring because its sizing differs from standard ring sizes. The listed model number includes size 10, so confirm the selected size before ordering. Some listing specifications are inconsistent or unconfirmed: the listed weight is 400 Grams despite the lightweight feature claim, the dimensions are given as 2D x 2W x 2H millimetres, and the listing names Bluetooth and NFC under communication features but lists Bluetooth as the wireless connection. Confirm these details if they affect your choice. Water resistance is described as both Waterproof and 100 Metres with an IPX8 rating, but the listing does not explain the conditions for those claims.
