The tracker itself could be well hidden and inaccessible to stop them finding it/smashing it.
Can't quite work this out but I left my battery in and have it connected to a permanemt live feed. After about a week I got a text warning of low battery, next day I went to check the unit and it was still showing powered up - and on my next 'call' it reported full battery ( and signal). I don't know whether this suggests it works off the internal battery until its low, then recharges from the lead ?? unlikely I guess but who knows the chinese. The test will be to see if I get another low bat warning in a week or so.
Has anyone found that the position accuracy is quite poor/variable - when sending multiple position requests I have found it to be up to 30m out at times.
The move alert also seems to have a delay and triggers 5-10 mins after it is moved............. however, still pleased as it will tell me when it has moved !
