I have to say that this tracker has been very useful. It's not only used for tracking but it also helps me locate my lost items quickly and easily. It works well when paired up with an app, which makes things even easier. There was nothing about the product itself that i disliked or found unhelpful in any way. For some reason, sometimes there is delay while using this device. However, after trying again, I realized that it was because of the network connection.
