Car trackers

Any one got one or tried one or have some first hand experience of Car Trackers
.
TrackR is Bluetooth connected, and when out of your range, it is viewable via any other registered user to show current or latest position.

These ones need a SIM, but can be good with a Pay as you go SIM, you send text and it reports back with a location and link to google maps. Some of them can alert you when there is movement, excessive speed etc. and even cut fuel or what ever if thats all wired in too

I have one that looks to be pretty much the same as this (similar price, also eBay) in my Spider. Just popped in a pre-pay SIM with £5 credit on it. You can configure it for live tracking if you have more data allowance, but I just have it set to the basic function.
All you do is to text the SIM in the tracker and it then texts back a link (URL) to google maps and information about speed and direction. If you have a smartphone, just click the link and, hey presto, you can see where you car is. Very good accuracy and no on-going costs as long as you keep the SIM topped up. I just have a Vectone one that came with £5 free credit that doesn't expire and it works a treat - as long as you can get a signal.

I 'won' something called 'Tile' a while back, i guess similar to the bluetooth device. Its OK if you have left something somewhere but if you want to be able to track something then you don't want to be reliant on another registered user with bluetooth being nearby..... unless they nicked it

I'd go GPS with a 5 quid giff-gaff sim or similar....
