The Macbook Air I purchased is working as it should so far.  The USB-C charger they included with the purchase however is not an Apple product and stopped working in less then 3 months.  I had Amazon contact them on three separate occasions and each time Kanga came back with a canned response and ducked their responsibility.  They claimed that a USB-C is an "accessory" and as such they are allowed to provide a "generic" USB-C charger.ACCESSORY: an object or device that is not essential in itself but adds to the beauty, convenience, or effectiveness of something else.I am quite positive that the ability to charge a laptop is ESSENTIAL!!!Putting aside the fact Kanga supplied a generic USB-C charger, they without my even asking, denied me a replacement of any kind,.  They said it was out of the 90 day warranty window. (which it wasn't).SHADY WEASELS is what comes to mind when I think about KANGA SUPPLY.Amazon made it right by giving me credit to purchase an Apple charger, which I am grateful. Hopefully they make Kanga pay.As for the MacBook Air, like everything except the keyboard which I real dislike.  The keys are too flat and makes it  too easy to accidentally hit an adjacent key.
