I bought this product from flipkart on 14th October 2018.
It’s been over 2 years and the product is working good in terms of charging and backup.
The material used is robust and it fell down a few times with no physical damages yet.
It’s charging time and backup is still like new although we have been using it constantly even at home.
The only cons I could count are
The power bank has a torch on the top. The torch went bad after a few days of purchase. Till then the power bank didn’t fell so the damage was not due to physical abuse. It was a technical fault.
The cable provided with the power bank didn’t last long and the same was of inferior quality.
The two reasons didn’t bother me as the product’s main function was absolutely working fine.
I recommend Ambrane power bank.
