Customer feedback describes the opener as easy to install and functional, with positive comments about scheduling, auto-close and appearance. Noise experiences are mixed, with some finding it quiet and others reporting screeching sounds. Value opinions also differ. This matters if you plan to use Silent Mode in a bedroom or are weighing the purchase against a simpler curtain control option. The listing's below-25dB claim is a manufacturer claim, not a guarantee that every installation will sound quiet.

Positive themes

  • Customers describe installation and general functionality positively.
  • Feedback mentions scheduled opening and closing and reports of successful Alexa use.

Negative themes

  • Some customer feedback reports screeching sounds during operation.
  • Some customers consider the product not worth its cost.

Mixed feedback

  • Noise feedback ranges from very quiet to reports of screeching.
  • Opinions on value are divided.
