brickhouse security Spark Nano 3 does not work , Internet

Spark Nano 3 does not work and they will not refund my money even though they cannot get it to work. They do not accept returns even if the equipment is defective they will not accept a return. But the Spark Nano 3 does not work as advertised. Even if you can get it to work intermittently, what it does work it does not report very good data. I used it on my car for several days and it only tracked about 50% of the time. I even offered to return it and buy something else from them that might work better but they would not accept a return under any circumstances. Just avoid dealing with this company.
