Review: Hendun Pool Gate Alarm - I purchased a few of these door safety alarms and its functionality is amazing. Very loud and can hear it from 100 yards away with loud noise if the alarm is triggered.. Excellent battery life and it was very easy to install.

It appears to be doing the job. The noise is very loud. The sound level is very high and good. So far so good I'll keep you guys posted. But yeah if anybody's looking for some kind of security alarm system that's affordable. I would definitely recommend this as it says what it does. And you just have to have that patience in setting it up. The information is easy on how to install. I did not use their tech support so I don't have a comment on that. But this is a very good and affordable product as it says what its going to do therefore i would recommend it. ## Frequently Bought Together - HENDUN Pool Gate Alarm Outdoor Wireless with Remote, 140db Loud, Waterproof Door Alarm Sensor, Kids Safety, Weatherproof Garage Fence Entry Chime (2 Pack) - HENDUN Wireless Door Alarms When Opened with Remote, Door Security Sensor, Pool Alarm for Kids Safety, Sliding (2 Pack) - HENDUN Wireless Remote Door Alarm, Windows Open Alarms,Magnetic Security Sensor, Pool Door Alarm for Kids Safety, Alzheimer's Apartment Alarm --- ## 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/201538249-140db-waterproof-alarm](https://www.desertcart.co.uk/products/201538249-140db-waterproof-alarm) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-04*
