SkyTag GPS Tracker....Anyone got one???

Just been flicking throw LRM and they have a article/advertisement for SkyTag GPS Tracker...
Its the normal kind of thing, you fit a tracker and if your pride and joy gets lifted. They can track it...

I'm tempted as with the number of Landy going missing on the up. My paranoia is growing.
Also they are doing a deal on them at the moment. (With a code in the mag)

So I was wondering if anyone has got one, how easy or hard was it to fit?
And the big question, anyone use it to get there Landy back??

One of my customers had one in his van (he didn't know he had it) big VW crafter, came out one day gone, called insurance company, hang on they said, yep its in bla bla street romford, fooookin ell how do you know that? it had a tracker fitted when it was new they replied, they called police when it stopped at a junction they disarmed engine (switched it off remoteley) how cools that apparently driver lept out when he couldn't start it again straight into the path of police car that was responding to insurance company call van recovered 4 hours after it was taken both theiving scum bags caught (one knocked down by police car not hurt unfortunatly)
