ANT+ compatible. You can display your heart rate on a cycling computer by long-pressing the screen on the heart rate display to enter heart rate transfer mode. I used this to display heart rate on the Garmin eTrex 30x handheld GPS, a product from the same company. There are bubble-like scratches on the top of the screen. It's a fairly old product, but the battery lasts for 4-5 days without being worn. I don't usually wear it, so I'm not sure about when it's worn, but the power stayed on even after cycling for 2 hours in heart rate transfer mode. The band is included, but I recommend replacing it.
