Amazon Basics Blackout Curtains vs Sun Zero energy efficient blackout curtain

The reviewers at The Spruce have featured the AmazonBasics Blackout Curtains Thermal Insulated, 2 panels in their AmazonBasics Room Darkening Blackout Curtains Review roundup. However, it fell short of making it to the top of their list.

As for the Sun Zero energy efficient blackout curtain - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.
