I am using Moto g5 plus since April. The phone is pretty responsive and is lag free but I have seen some minor lags when we play games or when we use some heavy applications. The sound quality of this device is okay and audible enough but when you are in a different room you might not hear the ringtone and you may miss your call.
The best part about the phone is its look and feel. Its completely fine with its design and weight. Its looks good enough and gives a premium feeling.
The phone on the other hand has a good battery backup which will last upto 1 day at least.
The phone price tag is a bit high according to the features given to the user.
Still its a good phone and you can go for it!
