About this deal
This deal is expired. Here are some options that might interest you:
Customs duty may be charged on top of the headline price, usually on items costing more than £135 Information
No idea how good or otherwise it is, but at 20 quid it has to be worth a punt, as colmi tend to be ok.
Voucher is auto applied at counter so with the tax it should show in total at 20.35.

sorted by£18.96 if you use Starling card and pay in US dollars. (edited)
I've had a Tapster payment ring since the back end of last year, registered to my Curve card
It still never ceases to amaze people when I pay with my magic finger
Best bit of kit I've bought in years, no more messing about with cards, wallets, phones, smartwatches just put your knuckles on the terminal and you're done
If you get one my tip is to get one for your dominant hand it'll just feel more natural when you reach for the terminal
You can measure the HR/other data of air or a carrot with it.
Much like with the chinese smartwatches..same scam..It's just software that spits out random reasonable looking value.
They put in Fake green/red blinking light in them lol...
Basically beware of any watch/ring that doesn't has continious Measurement but a one-off that you have to press to fetch value . Also if it says it has Blood Pressure - Run away, all of them are fake!

Physically impossible to take it it that extremity.
The concept of smart rings measuring blood pressure, much like with smartwatches, is not inherently against the laws of physics, but it does face substantial technical and practical challenges. The primary issue lies in the method required to accurately measure blood pressure without a traditional cuff, which is designed to momentarily stop and then measure blood flow.
Smart rings have even less surface area than watches for housing sensors, which could make integrating the necessary technology for accurate, cuffless blood pressure measurement more challenging. However, advancements in miniaturization and sensor technology could potentially allow for innovative approaches to blood pressure monitoring from smaller devices.
Several methods for cuffless blood pressure monitoring are being explored, such as:
- Pulse Transit Time (PTT): This method estimates blood pressure by measuring the time it takes for the blood pressure pulse to travel between two arterial sites. The challenge in a ring would be accurately measuring this time over such a short distance and with limited sensor capabilities.
- Optical Sensors: Advanced optical sensing technologies could potentially be used to estimate blood pressure by analyzing changes in blood flow or the behavior of blood vessels under the skin. However, the accuracy of these methods needs to meet clinical standards.
Smart rings could theoretically incorporate such technologies, but they would need to overcome challenges related to sensor accuracy, battery life, and the physical size limitations of the device. Furthermore, any device intended for medical-grade blood pressure monitoring must undergo rigorous testing and receive regulatory approval to ensure its accuracy and reliability.As technology progresses, it's possible that we'll see more advanced health monitoring features in smaller wearable devices, including smart rings. However, as of April 2023, such capabilities were still in the research or development stage, and no commercially available smart ring offered reliable, cuffless blood pressure monitoring that met medical standards. The field of wearable health technology is rapidly evolving, so future innovations could potentially change this scenario.
For people who are saying such a nonsense things I would advise just to buy it and test by themselves and if not liked, just bin it. It cost just 20 quid and that money easily goes in just one night at the pub. (edited)
Should have called it: COLMI Later or COLMI Ishmael though
