I'm definitely getting one. Canada is overreacting as most cars use rolling codes, but I have a shitty old aftermarket system and it should be possible to either A) Use it to unlock my car outright or B) program my car to accept it as a second remote. My car locks itself while running if you close the door, with this, I could (hopefully) heat up my car in the AM before driving to work, then just use this to unlock it! And if my fob's batts die it's less inconvenient until I can get the stupid AAAA batt or whatever it takes. Also gonna test my mom's garage door and use it if I can, and find out if my RFID blocking wallet works, and who knows! Might fuck around with some RFID too, gonna check my pet's tags, they might tell me my cat's temps!
