Ring AIR Sizing Kit | Choose from Sizes 5-14 | Sizing Guide for Your Smart Wearable Ring

Perfect smart ring, easy to set up, lots of different measurements to help you within the app to check progress or just general health, much less intrusive than a smart watch.

Very good and very reasonable price.

Very handy to have. At least you can size the ring correctly before you buy. And 20p is brilliant

Thickness of the ring to get use to it.

This sizing kit is simple but super useful. I tried it before ordering the actual Ultrahuman Ring, and it made the whole process stress-free. All the sizes are included, they’re comfortable to test, and it helped me find the exact fit in just a few minutes. The rings feel lightweight, easy to slip on and off, and give you a clear idea of how the real one will feel. If you’re planning to buy the Ultrahuman Ring, this kit saves you from guessing and returns. Worth it, quick to use, and does the job perfectly.

Arrived on time handy little kit used it to be a cheaper trial smart ring to start with

It's good

Fantastic idea so you can get the correct fit Super ideal as you can wear them for numerous days to ensure the fit is perfect also you get sample colours so you can see in hand what finish will look like and this is super handy as the pictures and reality are totally different in my opinion Overall a very good purchase as I know I will get the correct size ring and appearance so is a must if you are looking to purchase the Ultrahuman smart ring and at 20p a absolute no brainer

Ottimo è perfetto per misurare le dita prima di comprare qualsiasi anelli .

Super quick delivery and item as described

Feliz de haberlo comprado antes de comprar el anillo porque adivinen? Me hizo decidir no comprarlo. Es muy grande e incomodo para mi gusto.

Nice packaging and test sizes.
