It is important to know

Before purchasing the COLMI RING 2 size 8 lubrication ring, please note that choosing a smart ring brings certain practical advantages, but also a series of compromises in terms of functions, comfort and use in everyday life. It is important to align your expectations regarding activity tracking and assess how important the supported scenarios and the experience with the app are to you.

• Smart rings are a discreet alternative to smartwatches, but they typically offer fewer external features – choose them if minimal intrusion into your appearance and ease of everyday wear are important to you.
• The functionality and ability to track activity are closely tied to the manufacturer's app - check if there is an app available that supports your smartphone, otherwise the features will not work optimally.
• Although design and material contribute to comfort, the robustness of the ring is also key depending on how it is used, especially if you want to wear it for sports or everyday activities.
• The expected period between charges affects the user experience; if you want to track activities and sleep continuously, check the actual autonomy.
