Stolen vehicle tracking - installation firms?

[Harris_I]

Doesn't appear to have been discussed on PH before (what is wrong with the Search function these past few months?)

I want to install a SmarTrack Protector Pro to my car and am looking online at mobile installation companies that operate nationwide. The best value seems to be CATA, trackerfit.co.uk and trackingmycar.co.uk.

All look to offer the same service, so has anyone used one of these firms? Good and bad experiences? (If bad, PM me in case we fall foul of any forum rules).

Thanks
