The ASUS ZenWatch 2 might be a bit old at this point, but it actually still holds some of the same specs as other smartwatches on the market right now. On top of that, the ZenWatch 2 also will be getting the upgrade to Android Wear 2.0 fairly soon, Google has already confirmed that this is one of many watches set to get the upgrade. So definitely a good thing if you are looking to grab this one. This is a square-faced watch, but it still looks good because it has a slightly curved display. It does also have 4GB of storage and 512MB of RAM, so it can still run Android Wear 2.0 fairly well at this point. Currently, the ZenWatch 2 is only available in black/brown and dark blue. The straps are interchangeable, so you can buy another one from Amazon, if you don't like the one that comes with it.
Right now, eBay is selling the ZenWatch 2 for just $79.95. This is a manufacturer refurbished model, but it is also the lowest price a ZenWatch 2 has ever been, which is pretty impressive. Additionally it does come with a warranty, so if anything should go wrong, you can have it fixed without any issues. You can grab the ASUS ZenWatch 2 from the link below.
