### ⭐⭐⭐⭐⭐ Excellent product and price
*by L***L on 27 April 2021*

Installed 2x16gb into my new iMac i7 3.8. Improved performance as expected. Easy to fit I used wrist static leads to avoid static. To maintain best performance I used slots 1 and 3 as recommended. None of the videos on installing memory that I found advised that it can take more than 30 seconds to start to boot up while the new memory is recognised. Amazons price was very competitive for OWC which is rated highly for Mac upgrades
