I love that you can set multiple alarms for different categories of lighting, like headlights or interior light. If your phone/tablet dies in mid-night (or is not near to have access), it's so easy to send an email from my computer with all my settings! Highly recommend! We are running our first fleet with headlamp telesos but we've been using them as backups too since day 1 with great success! It helps us keep track of where everyone was during any given shift without having someone constantly monitoring their devices via cell signal. The only thing I dislike about this product is how much more expensive compared when I got started because now it seems as though they want $500+ per month instead of around 50 bucks at most places if not free at some sites - which isn't always worth paying for something just out right FREE otherwise you're wasting money The ease of use and the fact that I can be able to see my vehicle in my garage from anywhere in the world. Not being able to see my vehicle in my garage from anywhere in the world is a bit of a pain. Also, the fact that the app is not always available for me to use. I would like to have the ability to use this app in times when I am not at home. I can keep track of my vehicle while I am away from home.
