First of all you have to Motorola to commend what is possible for small money. Acceptable screen, smooth working, ordinary hapische quality of the housing. To criticize is only the vague and inexact side buttons without clear pressure point - but it all works. Making calls is ok, messaging is ok for little money. The camera is not great, but adequate.
Nett also the memory (RAM) of 1GB, which allows it to make task switching without complete new start of Apps and keeping more complex applications in memory (since siehts worse with my main device). The memory for apps and photos is limited, but you can with it and live with a memory card.
For ingress suitability should be noted that the lack of a compass in the Moto E already disturbs because it "experimental" have to find out in which direction the portal is or is currently running. Normally you can see with better equipment, the viewing direction vs. Portal direction, not here. Complex Card (IITC) can be displayed easily. GPS accuracy is worse than the iPhone, the position jumps more. That's a little whining at a high level - on the whole, the device is useful.
