I wanted to get alerts as the water was rising but before it spilled out onto the floor. The sensor having a long cord allowed me to do this. Most sensors have to have contact with the water on the sensor body in order to get an alert. I was also searching for a product that gave push notifications without a monthly subscription fee. The switch bot leak detector accomplished this. So far has been a great/ reasonably priced product. The setup was also very simple. Thanks! ### ⭐⭐⭐⭐⭐ Worked exactly as advertised *by on Reviewed in the United States June 10, 2026* Worked exactly as advertised. Since my HVAC unit is located inside my apartment, I decided to place one of these devices underneath it for added protection. The setup process was quick and easy, and the device supports Wi-Fi connectivity as well.After testing it, I received all notifications promptly and without any issues. Overall, it performs reliably and provides great peace of mind. Highly recommended! ### ⭐⭐⭐⭐ Would recommend *by on Reviewed in the United States July 2, 2026* I am not a techy and was able to set these up with relative ease. They are excellent at detecting water immediately. the problem is getting alerts (not alarms, but texts and emails) either because they have gone off-line or some other reason which I can’t explain. I like that they come with or without a cord that can get tucked in somewhere where the device itself cannot reach. despite the alerts mentioned, I am so happy with them because they bring peace of mind --- ## 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.tw/products/694253476-switchbot-3-pack-wifi-water-leak-detector-water-leak-sensor](https://www.desertcart.tw/products/694253476-switchbot-3-pack-wifi-water-leak-detector-water-leak-sensor) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-30*
