34in x 64in Black Cordless Cellular Shades TDBU - No Tools No Drill

In this review the LazBlinds 34in x 64in Black cordless cellular shade is judged on ease of installation, light control and daily use. The bottom line: this inside-mount, top-down bottom-up blackout shade is best for renters and homeowners who need real room darkening without drilling into frames; the single biggest reason to buy is the patented No Tools-No Drill system that installs in under a minute while still delivering full blackout and thermal benefits. The review focuses on practical fit, child-safe cordless operation and how well the honeycomb construction blocks light and insulates.

Key Features

• Inside mount only: The shade is made slightly narrower (a 3/8 in deduction) so the actual blind measures 33 5/8 in W x 64 in H and fits window widths about 33.7-34.6 in for a snug inside fit.
• No Tools-No Drill system: LazBlinds patented mounting uses an extendable spring rod to secure the shade without screws, making installation fast and leaving frames undamaged.
• Cordless TDBU operation: Top-down bottom-up control lets users lower the top or raise the bottom for privacy and light while keeping a child-safe, tidy cordless profile.
• Real blackout lining: A silver-plated interior layer blocks sunlight and UV, producing a darkened room suitable for daytime sleeping or media rooms.
• Thermal honeycomb construction: The non-sagging cell structure traps air to reduce heat transfer and dampen outside noise for a more comfortable interior.
• Strong hold for many surfaces: The spring rod can extend 1 in total and the mounting system supports up to 30 kg across common wall and frame surfaces.

Who It's For

The shade is a good fit for renters, landlords and anyone who wants blackout performance without modifying window frames, especially in bedrooms or home theaters where light control matters. Families with children or pets will appreciate the cordless design and the option to use the top-down feature for privacy while keeping daylight.

It is not suitable for windows that require outside mounting or where the sill depth is less than the minimum 1 1/5 in required for an inside mount. Buyers who need custom widths outside the 33.7-34.6 in fit range or who prefer motorized controls should consider other models.

Pros & Cons

Pros

• Easy, tool-free installation that protects window frames and can be completed in minutes.
• Effective blackout and UV blocking due to the silver-plated cell interior for true darkening.
• Child-safe cordless top-down bottom-up operation with flexible light control and privacy.
• Thermal insulation and noise reduction from the honeycomb cell design improve comfort.

Cons

• Fits inside-mounts only and requires a minimum frame depth of 1 1/5 in, so it will not work on every window.
• Fixed size and fit range mean customers must measure precisely; the spring rod fit tolerance is limited to about 1 in.
