I bought this phone more than a year back 32 GB model of Nexus 5.Phone quality is good and I bought it after success of nexus 4 and a google phone manufactured by LG both are good brands.Pros of the phone are good feature android phone with update comes early and makes phone as new look wise.Camera quality is good.
Cons:Battery life is less than day if your usage is high.I used a lot so face this issue of charging again in a day.
If you use cover the back side of the phone is so soft that after sometime when dust goes inside it scratches comes there with dust.So in that case require every week cleanness.
Beside every cons a great phone and must be get it checked for purchase.
