I bought the Aktiia (now HiLo) blood pressure monitor bracelet in November 2024. First off I bought the larger bracelet strap/band as i have Large size wrists. I would say that they really need to make a XL size strap/band, as even the Large band adjusted to how your supposed to wear it, it barely does up. Aside from this the Bracelet worked fine until about March 2025, then it started to have problems with connecting to the phone app for the Initialisation process. I tried everything to try and make it work, including contacting the company. Which brings me to my next problem, they are based in Switzerland I am in the United Kingdom. They don’t have a way to contact them apart from by email, which is not the quickest to try to troubleshoot your issues with their product. It kind of made me feel a bit uneasy about them resolving my problems. After several weeks of emails back and forth, with still no luck in getting the device to start working again. I decided to exercise my right to a full refund at the end of April 2025, thid process took over a month to complete and I finally received my full refund on the 5th June 2025. What I would like to see from this company, is a live chat option via the app and website, a contact phone number preferably a freephone one, a customer support centre to address customers problems. I would only consider buying another of these products from Aktiia/HiLo if they have the above things in place, and a much improved device. If I was to buy another device like this I would read as many customer reviews as possible especially the negative ones to determine people’s issues etc
