Worth it to get TAG system installed?

I have a 2020 Honda Insight Touring fully paid off. It’s only got 40000 kms on it so I’m planning to drive it for a while. I’m with TD and they don’t cover the installation and they will take 15CAD off the insurance every month. So it will take 2.5 years to recover the cost. I am thinking of getting it mostly for deterrence not that many people are looking to steal an Insight but who knows? It’s my first vehicle so I am trying to take care of it. Anyone with the system installed and are able to share their opinion? Appreciate it.
