## Customer Reviews

### ⭐⭐ It's been a couple of months, charge over-night, lasts 5 seconds.
*by A***R on April 17, 2024*

Possibly a bad batch of batteries?

### ⭐ WARRING!!!!!!!
*by R***E on April 21, 2020*

Does not respond to messages. Let not to cancel because I realised this battery is not razer oem battery. It's a razer clone/knockoff. Missing razer logo. I will be refusing order at door. Not Into cloned or knockoff products.

### ⭐ Looks like an OEM battery...
*by I***. on May 18, 2021*

Battery doesn’t even last a full day’s use on a full charge. My dead 5 year old (swollen) OEM battery lasts longer than this replacement
