Yes. You're eligible for what the company calls a "30-day risk-free trial" for any GetSafe package.
This means that you get to try the system for 30 days and return it without any penalty after the 30-day trial period. You may have to pay a prorated fee for the amount of time you used the system. This fee appears to be based on the $27.95 per month charge for 24/7 monitoring.
