Upon investigation I now realises the Vivosmart HR+ has a acrylic screen, one of the most unstable materials possible. For a watch to only last 1 year, only used while training is to say the least – rubbish. And that while I mostly play tennis (with my right arm and the watch on the left arm!) My recommendation is to rather inform possible buyers to 1) stay away from Garmin and 2) make sure you have at least a Glass lens because I can prove to you acrylic is useless. I have a laser machine and use perspex, and will never use acrylic because it is a very unstable product and is guaranteed to crack – it is just the nature of the product. And to pay for a watch after the previous one broke 3 days after the so called guarantee, is telling a story about Garmin’s commitment to client service – you decide yourself ….
