We had Vivint come to our door one night offering their full package system and a 10 day trial. So we had them install it and ensure we could cancel after 10 days if we didn't like it. We loved the system, but hated the contract terms. They were for 5 years, no cancellation options, at a very high monitoring fee but no up front costs except $100 for install. We decided that, as the monitoring times five years was a total of over $4200 that we felt it was too high and too large of a commitment. If we could have gone with 3 years we would have considered them.
It was a bit challenging to cancel and had to wait 3 weeks for guy to come uninstall (and would only do on a weekday). But we did get it out at the end of it all without too much hassle considering.
Great system and product, but very expensive. This company is out of Utah and not Canada, in case that matters.
Just wish they weren't double the cost of most companies and such a long term contract.
