Gionee Marathon M3 is best mobile for me. Because I used last one and half year and did not found any major issue related to product. Following majar aspact I most like in this product.
First thing is most like is bettery back. Two days I easly pass with one time bettery. As per my opinion, for a bettery back this model is best one. Other than it I did not found such experience.
Camera result and user friendly function.
Disply size
And I never seen that my phone has to hang for few minute. So smooth process working without stopping it is best for me.
I suggest to my friends if you go for long bettery backup than go with this model specially.
