Thats really cheap but I would still recommend the Tile over trackr. Tile has much better range and the battery life is incomparable. I dont care that trackr will give you a new battery for free, if it dies every 2 months then there is a much higher likelihood that when you need to find your keys the battery will be dead. And i dont want to worry about changing batteries every 2 months. Id much rather get a year of battery out of it and then change, even if I have to pay a few dollars for a new battery
