The Tracker
Problems
A real pain in the ass is it does not have a handy keypad locking mechanism. Every time one wants to lock the keypad, it is needed to go through a whole rigmarole of menu navigations to get to the option. Another problem is it quite often reports false alarms, which can be so annoying that you just want to turn the entire device off, making the thing pointless. I think this gadget does not worth its cost. I recommend to get a dog instead and train it to sniff all accessories you want to put a tag on.
