### ⭐⭐⭐⭐⭐ Super Great
*by M***E on September 23, 2025*

### ⭐⭐⭐⭐⭐ Using it for a VERY long time, legit.
*by J***N on April 11, 2025*

Using it for a VERY long time, legit.

### ⭐⭐⭐⭐ Poorly Designed but not their fault
*by C***N on June 20, 2025*

I've now on my third chargers on my Lenovo Legion. There is a well documented design flaw in the chargers where eventually the charger will be unable to maintain a connection. This will cause the charger to reconnect multiple times a second which makes the charger hot and throttles your laptops performance. Easiest way to tell if your laptop has this issue is by watching the charger indicator light flicker. I've had this happen with both the official charger and this one. The official charger from Lenovo costs $250.
