### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality for good price.
  

*by J***E on Reviewed in the United Kingdom on 20 March 2020*

Works a treat. My Dell G7 runs perfect now.Crucial makes its own RAM, so good price for a good quality product.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Huge upgrade - well worth it.
  

*by M***H on Reviewed in the United Kingdom on 30 December 2019*

Picked this up on a black Friday deal at the same price as the standard ram. Slightly less latency which makes for a sharper response. Fitted as an upgrade in a single-slot laptop from 8gb up to 16. Immediately notice that the fan runs less, and I'm not maxing out memory any more. Great buy of you're on the fence.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
