They are great and the beauty of them is that you can use them as often or as little as you want. Although some factory implementations are quite bad and make the remote starting pointless. Like Toyota had a brilliant idea to shut the engine down when the door is opened.
My Mazda's starter has a neat feature where if you started the car normally, or the key is already in the ignition and the car is not running on remote start anymore, you can still activate the remote start, remove the key from the ignition and leave the car running. Very useful for those very cold mornings when you have to run back into the house for whatever reason after starting the vehicle, less strain on the battery.
Also, remotes starters work best with automatic climate controls because you don't have to remember to leave the HVAC system in the proper settings for the next remote start.
