Cordless Blackout Cellular Shades 23in x 64in - No Tools No Drill

In this review of the LazBlinds cordless cellular shade, the bottom line is simple: it is a practical solution for anyone who needs a true blackout window covering that installs without drilling. The reviewer found the TDBU (top down bottom up) design and real blackout interior layer make it especially useful for bedrooms or media rooms where light control matters, while the patented No Tools-No Drill system makes it ideal for renters and homeowners who want a strong, damage-free fit. Installation, fit and light blockage are the reasons to consider this shade.

Key Features

• No Tools-No Drill system: Installs in under a minute without screws or brackets, so it leaves window frames intact and suits renters or frequent movers.
• Top Down Bottom Up: The TDBU function lets you lower from the top or raise from the bottom to balance daylight and privacy as needed.
• Real Blackout lining: A silver-plated layer inside the cells blocks sunlight and UV rays to create a dark room for better daytime sleeping or media viewing.
• Cordless safety: The cordless design provides a clean look and reduces entanglement risk for children and pets while remaining simple to operate.
• Thermal insulation: Non-sagging honeycomb cells trap air to reduce heat transfer, helping keep rooms cooler in summer and warmer in winter.
• Precise inside mount fit: The shade is made slightly smaller for inside mount installation and the spring rod can extend to fit a narrow range of window widths.

Who It's For

The shade is best for renters, landlords and homeowners who need blackout performance without altering the window frame, and for bedrooms, nurseries or media rooms where light control and safety matter. Families with kids or pets will appreciate the cordless operation and the quick no-drill installation that avoids permanent hardware.

This product is less suitable for windows that require outside mount options or for frames with less than the required 1 1/5 in depth for inside mounting. If you need a custom outside mount or a full-frame curtain-style solution, look for a different product designed for exterior mounting.

Pros & Cons

Pros

• Easy installation with the patented No Tools-No Drill system, often completed in minutes without tools.
• Excellent light blocking thanks to the silver-plated blackout layer, delivering near-complete darkness when closed.
• Safe cordless operation and versatile TDBU movement give precise control of light and privacy.
• Thermal honeycomb structure helps with insulation and reduces outside noise.

Cons

• Inside mount only and requires a minimum window frame depth of 1 1/5 in, limiting where it can be used.
• Shade width is slightly reduced (3/8 in) for inside mount fit, so careful measuring is required to ensure a snug installation.
