Aktiia Blood Pressure Monitoring System 24/7 Wrist Bracelet (Now called Hilo and works with the Hilo app). I bought this back in 2021 or so and used it for a while. I've sorted my blood pressure issues so longer need it. I tested it the other day and both parts (the wristband and the blood pressure cuff) are in full working condition, and it comes with the charger. I don’t have the box or instructions but these can be accessed online.
