Query: I'm a great gf

I bought this product for my boyfriend after he received 2 speeding tickets for going 30 over. He has a need for speed.. Well I was pregnant and we didn't have that kinda money to just throw away so I thought smarter and found him this radar. It's inexpensive and he loves how it works!! He can be speeding and it'll start beeping when the cop is 2 miles away! The cons I've found are that if you are in the city, it gets annoying because it beeps when you pass a automatic door. I find myself turning it off when I get in the city because I can't handle the excessive beeping. Also I think it only works if the cops radar is on u
