Ive had it on 2.5 years. Only prop i had was the installer put one of the immob circuits on the starter motor wire from the ign switch (the big black one on the mk2) and the wire was too small. Just changed where it was and worked fine again.
i also have it and it's a quality alarm!! I also got the duel proximity sensor fitted and it also is sh1t hot although it can take a bit of fiddling to set it up as if its too high heavy rain will make it send a warning (5 or 6 chirps) But once its sorted its a mean piece of kit!!!!! Any other questions just pm me as i done a fair bit of checking out alarms before i settled on the toad
Good alarm, mine has false alarmed 2 in three years and both times were my fault, though its best to get a good installer.
