Grandekor’s 35×36 motorized roller shade solves a simple problem: making a window dark without drilling holes or running wires. The mounting system uses a tension-based bracket that locks into place in about ten seconds. No screws, no anchors, no damage to frames or walls. For renters or anyone who doesn’t want to commit to permanent hardware, this is a genuinely practical solution.

The polyester fabric is a true blackout material. In testing, it blocked all direct sunlight, leaving the room completely dark during midday. The shade runs on a rechargeable motor controlled by the included remote or the Tuya smart home app. You can set schedules, adjust from another room, or use voice commands through Alexa or Google Assistant. The motor is quiet and responsive, and the 35-inch width fits standard windows without gaps.

One honest limitation: the battery is built-in, so you’ll need to charge it every few months depending on use. The shade is also manual-only if the battery dies, though the charge lasts through regular daily operation without issue. For a cordless, drill-free blackout shade that integrates with your smart home, this is a clean, effective option.
