This is the smart pet leash that pairs with a smartphone to track your walks and alert you to incoming calls, texts, and notifications. The ergonomic handle connects with a free smartphone app that tracks time and distance walked, records maps of routes for sharing with family and friends, and vibrates when you’ve reached your pre-set walk time goal. Incoming phone calls, texts, and notifications also cause the handle to vibrate so you can always stay in touch. In tests by The Hammacher Schlemmer Institute, analysts noted the leash is a great way to “meet your pet’s—and your own—exercise needs.” A built-in LED flashlight and light ring around the handle’s circumference provide visibility during nighttime walks. The tangle-proof 44" nylon leash fully retracts into the handle that has a rubberized grip for assured handling of the dog. Recharges via USB with included cord. Handle: 4 1/2" L x 4 1/2" W x 1" D. (4 1/2 oz.)
