I barely notice the device, and I like that the components can come apart using a magnet, which makes it easy to put on and off (especially if I am wearing laboratory gloves with the device). While the magnet feels secure, I am concerned of losing the magnet attachments if I accidentally hit my device on anything. It is light and comfortable to wear and has not interfered with my daily activities. I can imagine that wearing a wrist brace alongside this device may be more difficult to use - perhaps having options to attach the magnetic components to the brace without a glove would be a future endeavor? Either way, I really like the device and would love to see it be functional. Great job guys!
