I just literally received the device and I am reading the user manual which states the product needs to be registered within 14 days to activate the lifetime warranty. So I am completing the registration before I forget. However, it will not allow me to submit the registration unless I leave a review. Since I have not used the device and I am being forced to leave a review before using it, I will be giving it a one star. In the future, I recommend not forcing a review.
