Once you buy an Nexus is always a worth of buying a phome like this. Nexus is one of the main company of the android actully Nexus is the first one to lanuch Android plateform and it is google base comapany so you can trust Nexus rather than other company.
Nexus 5X is the second gen of the first nexus 5 with improve specification and the bugs of Nexus 5 are remove in the Nexus 5x. The phone is pretty awesome in look as well as in specification. The degisne of the Nexus 5x is different from the last Nexus 5 and material used in the Nexus 5x is better than the Nexus 5
Meanwhile according to Nexus 5, Nexus 5x comes with some pretty good specification like
5.2 IPS LCD display with 16M colour
Snapdragon 808 with dual chipset of 1.4ghz quardcore cortex A-53 and dual core 1.8 ghz cortex A-57
Android 6.0 with updates
12.3 MP primary and 5.0 secondary camera
Fingerprint scanner
Internal 16/32 gb with 2GB Ram with no card slots
The only drage that I have been seen after the specification is that the Nexus is providing only 2GB Ram which is not good enough because some other phone have almost 3-4 GB RAM with cheap rate. Other wise phone awesome and very handy and also very good in looking.
