They’re very loud for as little as they are, Also love the different sounds that it and has a very easy to operate. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Very good *by N***E on Reviewed in the United States on July 2, 2022* This is a very good little motion detector sensor for the money. We recently had our pool installed & this was the sensor our builder got us. It came with 2 separate sensors. We installed 1 on our sliding back doors & 1 on our basement door. It works for sure, but the best part about this style sensor is that it’s super easy to turn on & off. You just slide the button up or down & it’s easily reachable while attached to the door. We have a very large home but this is pretty loud. You will hear it for sure. Also, it does not sound like any other random device when it goes off. So it’s got it’s own sound, which is very nice. In other words, you won’t think eh it’s just someone’s car alarm or phone or something else. No. You know it when this thing goes off. If you have children, this is a great little device to install on your doors. And when I say install, I mean, simply load it with the right batteries, stick it up on your door & slide the button to activate. Super simple. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Is your door frame flat? *by J***N on Reviewed in the United States on June 3, 2024* Bought this to keep my husband inside at night, he has dementia. Was unable to install 1/2 of the magnet door the door frame because the frame does not have a flat surface. Otherwise I think it would have worked --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/431475177-secrui-door-alarm-for-home-security-window-sensor-120db-4](https://www.desertcart.co.uk/products/431475177-secrui-door-alarm-for-home-security-window-sensor-120db-4) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
