Reconsider using Tracker

The low rating given by other people is very accurate!! The systems they have in place don't work. The key tag keeps having malfunctions and trying to get it sorted is a nightmare (staff are not helpful). Nevermind the fact that they say the system might not work if you have an emergency (hence why I'm struggling to sort the problem out, but the sentiment is not shared). Really, stay away, consider other companies before them.
