100% Blackout 66in x 78in Top Down Bottom Up Cordless Cellular Shades

In this review the BERISSA 66in x 78in cordless cellular shades are evaluated for bedroom and living area use where full blackout and easy, rental-safe installation matter most. The single biggest reason to buy is simple: these shades combine true 100% blackout performance with a dual-mode top down bottom up design and a no-drill installation that preserves window frames. The reviewer's experience showed strong light blocking, clear thermal benefit, and a straightforward self-install process that required only the included wrench and a few minutes per shade.

Key Features

• Dual-Mode Operation: Top down bottom up tracks allow sunlight in from the top while keeping the lower area private, or full lower closure for complete darkness.
• No Drill Installation: Lateral tension brackets mechanically anchor to frames for a drill-free fit that is removable and rental-safe without surface damage.
• 100% Blackout Fabric: The honeycomb core blocks light fully when lowered, making the shade effective for bedrooms and media rooms.
• Energy Saving Honeycomb: Cellular construction traps air to provide insulating benefits that help cut heating and cooling energy usage.
• Cordless Child-Safe Design: Smooth hand-pull operation eliminates dangling cords and gives a clean, modern appearance.
• Quick Self-Install: Brackets and hardware are designed for a fast setup that customers report as easy and repeatable across multiple windows.

Who It's For

This shade is best for renters, homeowners, or anyone looking to convert bedroom or media windows to full blackout without drilling into frames. The cordless, tension-mounted system makes it especially appealing for those in apartments or rental homes who need a removable, no-residue solution.

People who need custom shapes, motorized control, or very unusual window sizes should look elsewhere, since this product is designed for standard rectangular windows and manual cordless operation rather than power automation.

Pros & Cons

Pros

• Excellent light blocking with true blackout fabric for better sleep and dark media rooms.
• Effortless no drill installation that customers consistently find quick and damage-free.
• Noticeable thermal benefit from the honeycomb construction, helping reduce heating and cooling needs.
• Clean cordless look and smooth operation suitable for families and children.

Cons

• Limited to manual cordless control, so it lacks motorized convenience some users may prefer.
• Best for common rectangular windows; unusual frames or deep sills may need alternate mounting solutions.
