Perfect for the price
For $215, you really can’t beat this for the latest Apple Watch. The packaging it came in was not pretty and the watch itself didn’t have that pristine new look, but I’ll sacrifice having to wipe off a few fingerprints to save that much money. My watch functions perfectly. I did get a protective cover for it. Very pleased with my purchase!

Great watch!
I had purchased this watch to replace the gen 1 watch my wife had. About every feature of the apple watch has been improved. ECG feature is pretty neat, and the display is awesome.
