Great purhase! - Great purchase! The Apple Certified Refurbished Series 9 arrived in great condition and works as expected. The 45mm size is comfortable, and the Midnight aluminum case with sport loop has a clean, simple look. Performance is smooth, and GPS + Cellular functions without issues. Good value for a refurbished device.

Wrong Band - The watch has to be charged everyday. Still learning about all the settings. I thought I would get the watch pictured ,the band was different. Customer service would not send the correct band. Had to go to local Best Buy and they took care of it.

Battery health is 100%. I use it in theater mode all the time and getting 40 hours. It has double tap control, hypertension etc. 95% of what series 11 offers at half price.
