Krown Door Knock Alert Flasher

In the product reviews, customers have expressed mixed feelings regarding the performance and functionality of the door knocker device designed for those with hearing impairments. A significant advantage noted is its effectiveness in alerting users to knocks, particularly for those with cochlear implants or hearing challenges. One user highlighted the bright strobe light as a reliable notification system, especially in an environment where sound is not an option. This feature was especially beneficial for a user's deaf son, who found the device to be a great solution, appreciating its portability. However, customers have also reported some drawbacks. There were mentions of the device being overly sensitive — even minor movements could trigger the alert, leading to frequent notifications that could be disruptive, particularly in spaces like vacation rentals. There were also concerns raised about the battery life, with certain users noting that batteries only lasted about three weeks, which could necessitate frequent replacements. Additionally, one customer experienced initial difficulties with the device not working after replacing the batteries, though this might have been an isolated incident. Overall, while the device serves as a helpful tool for those with hearing impairments, its sensitivity and battery longevity may require attention and could affect user experience. **
