When I read the prompt, I rushed to go read through other entries first for one reason. I thought it'd be weird for me to write that I won't buy the machine even if it's very cheap or use it if it's free of charge to check. But reading through others entries, we are well aware of the dangers.
Death is inevitable, while we could to good extent determine when one can be born, it's never told when exactly they can be born and same for death. When people fall seriously sick, doctors or people who are good with health issues can give an estimate of time left for these people to live.
Most of the time, they are never accurate because death is meant to be unexpected most times. Though it's sad to think, death doesn't care about age, achievements, morals of being good or being bad, it just comes to whoever it wants at the appointed time. Many lost lives even in sleep.
It has been like this for millennium years, since the beginning of the world, since Adam. And now, humans have developed a device that can tell me the time of my death? That sounds like a whole deviation from what the world has been created to be, it will cause a huge disaster in the world.
Why I think so is not far fetched, we've see how people act after they get the news that they will die in less than six months time, they tend to live so cautiously like it's not life they are living anymore. Some even die way earlier before then because they let fear kill them before the illness.
And then, let's talk about the part where this device will make people lose hope so easily because one of the reasons we are all living and waking up each morning is the hope that we have that the new day is another opportunity to get something right. Knowing when to die takes that.

Instead of buying a device to know when I'll die, I'd rather live right for the case of dying so unexpectedly or by accident and take care of myself for the case of growing old before death. We don't need to know how long we have to live, what matter is how we live the life we have now.
I guess this where the life advice of: "Do It Now" works very well. We don't know what will happen the next hour, we only know today so today is the right time to start what you've been procrastinating on to start. Devices will only tell you when to die, not how to escape it so no need.

That's just what I'd do myself, better to life my life to the fullest, than live in anxiety that follows knowing the time of the inevitable.
Yeah, it doesn't sound peaceful at all.
