Black Roller Shades 35in x 72in - No Drill Cordless Blackout

In this review the Persilux black roller shade (35in x 72in) is evaluated for homeowners who need an easy, no-tools blackout solution for inside-mounted windows. The bottom line: this shade is for anyone who wants near-complete darkness and fast, damage-free installation. It installs in under a minute using a no-drill device and a tension mechanism, and its 100% blackout fabric with thermal coating makes it a practical choice for bedrooms, media rooms, or doors that need privacy and light control.

Key Features

• Size and fit: The blind is sized 35in x 72in with a fabric width of 34.2in and a top extender that adjusts up to 0.5in to fit window widths between 34.5in and 35in for inside mounts.
• No tools installation: Installs in under 20 seconds without brackets or screws, so it avoids damage to the window frame and allows easy repositioning.
• Cordless free-stop design: The spring glide system lets the shade stop at any position and reduces cord hazards for homes with children and pets.
• Full blackout and privacy: The blackout fabric blocks light fully and the built-in thermal coating adds UV protection and insulation benefits.
• Portable and removable: Tension mechanisms make the shade simple to remove and reinstall, useful for renters or those who change window treatments often.

Who It's For

This shade fits people who need a quick, clean blackout solution for an inside-mounted window with at least 2in of frame depth. It is especially well suited to renters, parents, and anyone who prefers a cordless setup for safety and a neat, fabric-front appearance.

Those who need an outside mount, custom width overhangs, or a shade wider than 35in should look elsewhere, since this model is intended strictly for inside mount windows and has a fabric width of 34.2in that fits into a narrow 34.5in-35in window opening.

Pros & Cons

Pros

• Fast, tool-free installation makes setup painless and noninvasive to frames.
• Effective blackout performance with thermal coating improves sleep and reduces light bleed.
• Cordless free-stop mechanism is safer for homes with children or pets and provides smooth operation.
• Removable and portable design adds flexibility for renters or multi-room use.

Cons

• Designed only for inside mounts and requires a minimum 2in frame depth, so it will not work on all window types.
• Fabric width is 34.2in which leaves little tolerance; some customers reported a too-narrow fit in certain frames.
