+1 to this. I didn't do enough research and ended up in a 3 year ADT contact with their extremely dated equipment back in 2016. Eventually I just stopped using their equipment all together and removed all of the sensors and switched to Google Nest products. Terminating the contract required paying off 75% of the remaining amount so I ended up just paying monthly on a service I never used because of how pedatory the contract was.

It's bad enough that you chose it. When I bought my home, one of the conditions was that I take over the contract from the previous owner. I thought that was kind of BS but ADT made it clear that someone would have to pay and the seller made it clear it wasn't going to be her. I ended up paying her to do the cancellation fee so I could avoid getting in bed with ADT.

Heh, I bet the seller was happy to get out of that.
