Very happy with my new treadmill and the speedy delivery!

My treadmill arrived WAY before it was estimated, which was a delight for me. It came in as advertised except that it had the old console that didn't include the Bluetooth link to the app, which the Lifespan company promptly replaced for me. I've been using it daily during my work hours and am very pleased with Standing Desk Nation and Lifespan.
