Blackout-Black 17in x 39in Cordless Honeycomb Shades - No Drill

Our review of these honeycomb blackout shades finds them ideal for renters, shift workers, and anyone who needs reliable darkness without altering walls. The single biggest reason to buy is the damage-free, 30-second installation system that really works as described: no screws, no tools and no holes. In real rooms the blackout fabric blocks light effectively, while the cellular design provides noticeable thermal insulation, making them a practical choice for bedrooms, nurseries, and home theaters.

Key Features

• No-drill installation: The included no-screw mounting system installs in about 30 seconds, so there is no wall damage and tenants can remove them easily.
• Cordless safety: A spring-driven cordless operation creates a quiet, smooth glide that is safer for children and pets than corded blinds.
• Blackout performance: Thick blackout material and precise fit stop most incoming light, improving sleep and screen viewing in media rooms.
• Thermal insulation: The honeycomb cells trap air to reduce heat transfer and help maintain room temperature year round.
• Durability: A lamellar spring system and rust-proof aluminum frame are built to withstand frequent lifts and long-term use.
• Custom fit reminder: Widths are cut 3mm smaller by default to ensure a neat fit, and custom sizing is available with double-confirmation before production.

Who It's For

These shades suit renters, apartment dwellers, and families who need easy installation and a nonpermanent solution that still provides strong light blocking and some sound dampening. They are also a good pick for bedrooms and nurseries where cordless safety and quiet operation matter.

People who need complete blackout with heavy room-darkening for professional photo studios or those who require motorized, remote control operation should look elsewhere; this model focuses on cordless manual operation and a damage-free mount rather than motorization or exterior mounting hardware.

Pros & Cons

Pros

• Quick, tool-free installation that leaves no holes or marks.
• Effective blackout and measurable heat reduction from the cellular design.

Cons

• Some users report mixed impressions of stability depending on window depth and exact fit, so careful measuring is important.
