Cordless Cellular Shades Blackout 20 in x 36 in - No Tools No Drill

In this review the LazBlinds cordless cellular shade stands out for renters and homeowners who need true blackout performance without tools or permanent hardware. The biggest reason to buy is the patented No Tools-No Drill system paired with a real blackout silver-plated cell that blocks sunlight and UV, delivering dark rooms and thermal insulation while installing in about 30 seconds. It is a practical option for anyone wanting a clean, cord-free look and straightforward inside-mount fit for a 20 in x 36 in window.

Key Features

• No Tools-No Drill installation: The patented spring-rod system secures the blind without screws or brackets, so fitting it takes about 30 seconds and avoids permanent holes in the window frame.
• Made for inside mount: A standard 3/8 in deduction is applied so the actual blind measures 19 5/8 in W x 36 in H to fit a 20 in W x 36 in opening precisely.
• Adjustable fit: The unique spring rod can extend about 1 in total, allowing the blind to accommodate a window width range near 19.7 in to 20.6 in for a snug inside mount.
• True blackout performance: A silver-plated layer inside the honeycomb cells blocks sunlight and UV for daytime sleeping and improved privacy.
• Cordless, child-safe design: The cord-free operation offers a tidy appearance and reduces hazards for children and pets while still moving smoothly up and down.
• Thermal and sound insulation: The honeycomb construction traps air in cells to reduce heat transfer and soften outside noise for added comfort year round.

Who It's For

The LazBlinds cordless cellular shade is best for renters, landlords, and home buyers who need a noninvasive solution that requires no drilling and can be removed or repositioned without damage. It also suits families who prioritize a cordless design for child and pet safety and anyone seeking solid light blocking for bedrooms or media rooms.

Those with unusually sized windows, frameless glass, or an outside-mount requirement should look elsewhere, since this model is built specifically for an inside mount and relies on the spring-rod compression fit to hold securely against the frame.

Pros & Cons

Pros

• Easy, tool-free installation that works in about 30 seconds and avoids drilling into frames.
• Real blackout inner layer that effectively blocks sunlight and UV for daytime sleeping.
• Clean, cordless appearance with smooth raise and lower action and good fit for standard 20 in x 36 in windows.
• Honeycomb cells add thermal insulation and some noise reduction for year-round comfort.

Cons

• Designed specifically for inside mounts with a small width deduction, so it is not ideal for outside-mount needs or nonstandard openings.
• The compression fit relies on proper frame depth and surface; extra-rough or unusually thin frames may reduce holding strength.
