Use it to replace my lost one, work like a charm and it's practically the same thing really!
It does what it has to do. The case is good and strong but could be better styled. Arrived as described. Performed flawlessly. Great value for a backup
I have been using the last 8 months no problem detected, working as the original one.
Very nice product. A perfect replacement for my laptop. I received it on time.
Excellent product with good charging support, Supports my Thinkpad laptop.
I thought it could be an OEM product but it turned out to be the original Lenovo product with a warranty of 1 year. Highly recommended.
