Yes agreed, I have it but for insurance purposes also had to have a tracker which is monitored 24/7. Suggest you ask VanBlitz about that. I found them very good and helpful. I had the whole lot fitted including Growler. Cannot say how effective they are as so far, touch wood, have not had someone try and steal the van! Given the cost of the home worth the cost!there is really only one i would recommend having had it fitted to all our vans to date. that is Vanbitz, Strikeback or if you have deeper pockets Growler.
they will also sort the tracker.
